Still one of the most informative, no BS channels on YT. Makes some damn fine pedals to boot. Thanks for all that you do!

Those of a certain age know well that actually ALL power is daisy-chained. Everything in your house or apartment is common from a single source feeding the building, and all the buildings on your block are being fed by a common source as well. Fifty years ago, if my mom was using the sewing machine, or the compressor in the fridge went on, the static noise created by motors messed up pretty much every audio appliance in the rest of the house - guitar amp, stereo, radio, tv - because those various motors produced spikes on the shared power line. Since that time appliances have been designed to minimize such problems arising from shared daisy-chained power. In the last 20 years, more and more pedals are digital in nature, with high-frequency internal clocks that, just like mom's sewing-machine motor, produce spikes on the power lines. The spikes are at such a high frequency that you won't/can't hear them. However, spikes on the power lines can produce a kind of ring-modulator effect when they meet, termed "heterodyning". This results in the sum and difference of the two clock frequencies being produced when they meet. If you can't hear a 2megahz buzz, then you most certainly won't hear the buzz produced when two high frequency clock spikes meet and sum. Their difference, however, is another matter. For example, if one pedal is running at 2.01mhz and another at 1.99mhz, they are both *nominally* running at 2mhz, and easily meeting a precision spec that says they aren't more than 1% off from their nominal frequency. They sum to 4mhz, *BUT* their difference is a mere 5khz, which you most certainly *WILL* hear. Power filtering on appliances like sewing machines, fridges, and TVs, power supplies has been adapted over the years to insure that spikes from one are not impacting on any of the others. For some of the earliest digital pedals, they would run blissfully silently on their own, but if you stuck two on a pedalboard, and made them share power, all hell broke loose, and people would complain about a "wasp's nest" of buzzing, often returning pedals to the store under the assumption that something was wrong with the pedal. In fact, the problem was digital pedals sharing power lines, and interfering with each other like mom's sewing machine did with my amp. There were several avenues to fix this. One was to use power supplies that provided isolated outputs such that no output could interfere with any other. The other was to design digital pedals to prevent clock spikes from exiting the pedal on the power line. Earlier digital pedals tended to lack this, though in response to customer complaints probably anything made during the last 8-10 years likely has built-in protection against power line noise and heterodyning. One could, in theory, daisy-chain such pedals without fear of noise. But their current consumption is likely high enough that two or more on the same power line is likely to exceed available current.

The point I made is correct, but the math certainly isn't! In fairness to myself, I wrote the original comment while coming out of the sedation (and prep day!) from a colonoscopy. Plays havoc with your math skills. The difference between the two clocks described would be 20khz, which you wouldn't hear. But suffice to say that digital pedals will have more than one clock in them, or rather a master clock divided multiple ways, with many possibilities for heterodyning products to be audible. That's why running two slightly older digital pedals on a shared power line produces a "wasp's nest" sound: many *different* high-frequency heterodyning products. Note as well that many higher-current wallwart supplies are of the "switching" variety, which also have clocks in them, as do many analog time-based effects like flangers, chorus, and delay. There are a great many possibilities for clocks in different appliances to duke it out on a shared power line. Best to keep them out of each other's way. If you're at NAMM, Brian, have fun, and I hope Terraform makes a big impression.

Thank you! Love my equator and your videos!

TLDR: don't use daisy chains if you can help it. The results are awful. Here's the deal with any audio equipment, and this applies across the board, and you don't need any deep knowledge to keep this in mind: You want to avoid any situation where you have both the signal grounds and power supply grounds connected together across two or more pieces of gear, as this will introduce noise, especially with unbalanced audio connections such as is used on guitars. Electrical isolation is key. This is why good power supplies have multiple outputs that are isolated. This is also why various boxes are available that can electrically isolate your signal, and why many DI boxes have a ground lift switch. If you daisy chain several pedals, the power supply ground is connected together between the whole lot, and so is the signal ground. This introduces what is called ground loops, where the two grounds form a closed circuit that allows small currents to flow. This introduces all kinds of noise issues from external sources such nearby equipment and appliances, nearby wiring, as well as RF noise (Yes I've picked up AM radio stations with my pedalboard). It also introduces power supply noise, and interference from other pedals, so a classic issue is digital pedals introduce switching and clock noise into the chain via high gain pedals. I get this is repeating what Brian said, and of course he knows his stuff, but I feel he and many other knowledgeable people online are struggling to explain these issues in layman's terms. He himself admits the difficulty with it. The big issue is that the explanation depends a lot on the knowledge level of the recipient, which in this case is a large audience that varies between extremely knowledgeable to no knowledge at all. I'm have some electrical/electronic engineering background with a deep interest in audio. Noise problems and "tone suck" are also two problems I have successfully solved several times, so if anyone is having these issues feel free to ask me. The internet is great for this kind of stuff.

Thank you for expounding on what Brian said and I do need some advice. I've slipped into a slow journey of designing my first pedalboard, born out of disappointment with multi-effects which I've used since the 90s, and amazement of individual pedal quality. I've pretty much settled on the ones I plan on using (about 8-10 devices requiring power) and in which order. My final factor landed me here. Power. CLEAN power. Unintended noise of any kind makes me crazy. My favorite effect is reverb, which unfortunately reveals the most noise. I've already confirmed the noise is not coming from my guitar or bass, as they are clean when going directly to their amps. The two types of devices I plan on using to prevent noise are a pedal board power supply, such as the Gator G-BUS-8, and plugging that into a power conditioner (such as Panamax). Now if execute on this, do those pedal board power supplies handle pedals with different amperage? Some pedals are the standard footprint, others are 2 to 3 times the size. In the end, people clearly have negotiated this obstacle as I've seen many concerts where all guitarists and bassists have large board setups without a trace of hum, hiss or buzz. Thoughts?

@Patrick-857

@@johncbeer A power conditioner could be a good idea, but in my opinion one should start with the basics and get them right first. Isolated power supply is a must for low noise. The Gator Gbus 8 isn't isolated as far as I'm aware from the forums, it's a 9v and an 18v daisy chain in a box. I'd love to be corrected but this is the info I have at the moment. I would recommend Voodoo Labs, Joyo or 1spot but there's tons of brands out there now. Strymon has one now. Pricey, but it has one of the highest milliamps ratings of any supply I've seen, and it's expandable. Power conditioner, in my humble opinion is not necessary if you have a good power supply, because the supply should do that job itself. Power conditioning amps is another story, and you could benefit from doing that. The other thing that helps a lot with noise, tone suck and the potential for pedal failure stopping your gig, is a pedal switcher, or looper as they're sometimes called. This takes unused pedals out of the circuit. Cheap ones are basically a row of true bypass switches, and they work fine, you can even make one yourself. I have a Free The Tone ARC-53M. This uses relays, and has an incredible buffer circuit that fixes long cable issues and enhances tone, it can be programmed with patches, can control pedals like the Strymon Timeline via midi, and it can itself be controlled by midi. It can also control your amps foot switch system as well. A good buffer at the start of your chain, and possibly at the end of the chain as well is also important, not so much for noise, but for tome quality. It can be just a pedal that is buffered bypass but with a really good buffer, or a dedicated buffer, or in my case my pedal switcher, which is a one stop shop. Some old school fuzzes and wahs don't like a buffer being fed into them, they want to see your guitar pickups directly, a lot of high end switchers have this taken into account with a dedicated loop that has no buffering. The next thing is a noise suppressor that can be used in the 4 cable method which has a send return loop that you put all your non time based effects into. Another thing, use good patch cables, keep them as short and tidy as possible, keep power away from signal where possible, and where a power cable and an audio cable meet, have them cross at 90 degrees or thereabouts, not parallel with each other. Also keep high gain pedals, especially hand made fuzz boxes with really basic circuitry away from the power supply if possible, it's not a major issue, but these pedals don't exactly have low noise circuit design, they pick up everything. Your question regarding amperage should not be an issue with most good quality power supplies, but check the specs, most of them will have a range of different outputs that support different amounts of milliamps, and the more recent the model the more likely it will support big digital pedals that draw 500mA. In summary, quality isolated power is number 1 priority, and some manufacturers are sneaky about whether their product is actually isolated, either making no mention, or having only s couple of isolated outputs split into lots of physical jacks, so they can get away with claiming it's isolated, when it's effectively several separate daisy chains.

That's a really good point at the end, there. Every one of those 100uF, 220uF, and beyond, input capacitors just got paralleled together with the daisy chain wires. Worse yet, those wires have non trivial resistance with each of those input capacitors, so that might make a bunch of unintentional Pi CRC filters on the power rails. Very good point indeed. Also true of your digital pedals and pedals with noisy oscillators like Flangers and Choruses in what you said as they can introduce heterodyne whining into the power rails too.

Sounds sub optimal, because you will still have ground loops because of the daisy chains, but you can probably avoid the worst of it by having your power come from batteries rather than mains. I would at least try to isolate your digital pedals from your analog pedals, especially dirt pedals. Digital pedals are themselves the most noise resistant, but also create the most noise in other pedals. I find they tend to be delays and reverbs ect at the end of the chain, so any noise they pick up is negligible. Dirt pedals on the other hand don't create much noise but they pick up the most noise. I've had not to many problems daisy chaining dirt pedals, but with each additional one you tend to get a slight increase in noise, and it all accumulates, resulting in a rig that has a lot of noise, but no single pedal adds much, making diagnosis impossible. I have a pretty big board, and it's very low noise even with very high gain pedals, because I spent a lot of time working out how to get it low noise, as well as low "tone suck". Low noise is possible.

I agree completely. Instead of a daisy chain, go with a dedicated power supply. The power supply I use is the Strymon Zuma.

I cut my daisy chain ends off and found random old power supplies connected them together. The noise was horrible with any of my pedals with them all strung together. Isolating the power supplies was the best way I found.

@@BeeJonez Noise gates absolutely fix the issue, but you want to start with a low noise rig, and add the noise gate on to compliment it. No use trying to fix a rig that's set up wrong and giving you lots of unnecessary noise with a gate. I use the Boss NS2, which many people dislike, but I love. I strongly recommend putting a noise gate that can be used in the 4 cable method on your board, and put all your dirt pedals and non time-based pedals (compressors and EQs are terrible for introducing hiss too) into the loop of your noise gate. So with the NS2 guitar goes into the INPUT, then out of the SEND to the chain of noisy pedals, and then from the chain of pedals back into the RETURN, and then the OUTPUT goes to your amp or to your delays and reverbs. The beauty of this system is the gate is triggered by your naked guitar signal but is clamping down on the noise of the pedals. Your pedals could be making noise that's louder than your guitar, but nothing but sweet sweet silence will come out unless you pluck a note. If you use the two cable method, the gate is simply being set to cut off any sound below a certain volume, and this sounds awful, and is either completely ineffective or very intrusive depending on settings. With 4 cable, you are starting with the cleanest possible signal, and using that to control the gate, not some arbitrary cutoff level. My rig is very silent, but my NS2 never feels like it's turned on. It just magically eliminates noise. It's also useful for something like a self oscillating fuzz like some of the Devi Ever ones with the "chaos" mode. These pedals actually make more sound (more ear rapey sound too!) when you are NOT playing. With these in the NS2 loop, they are silenced when I'm not playing, making the horrible noises much more useful.

Great video!

Great video as I thought my daisy chained supply at times wasn't pouring the balls to my pedals consistently !!

Thanks this helped ill upgrade when i notice problems then

Thanks Brian.

perfect explanation

I’m using probably three daisychains on a board with 32 pedals,with 3 -1 spot adapters, quiet as a mouse if you do it right. I put my sons paddleboard together with the nice VUDU lab power, because he likes to be sure, but if you take your time sometimes the one spots will work for you.

In the case of the 1Spot, exceeding the max mA will cause the 1Spot to turn off. When you unplug enough pedals to reduce the load to below the 2amps it will turn back on and power the remaining pedals. As far as noise True Tone has demonstrated time an again that it’s as quite as a PP. There are instances with certain pedals that can cause noise (hiss, whistles etc. depending on the pedal) when daisy chained.

I don't use Daisy chains any more I only use isolated power supplies. Great analogy.

Thank you!!

"Now, daisy chains... "

Thanks Brian. Great info. Do you make a pedal that gives bass that warm break up (clipping) sound like Bernard Edwards bass on I'm Coming Out by Diana Ross

great info as always, quick question, my pedalboard is powered by a dc brick by mxr. it doesnt have a power switch so it always on, is it okay to leave the power plugged in while all pedals are turned off when im done playing or should i unplug the power supply every time im done?

It might be helpful to talk about using a power supply in terms of adding up current load (milliamperes) for the power outputs. For example, I have an “isolated” power supply with multiple outputs. Half are 100 ma - enough for at least 1 typical analog pedal. Others are 250 ma. I only have 1 pedal that draws over 100 ma (Echoplex), but I could do a small daisy chain off of each of the other 250ma outputs. Also there’s some experimentation required. I’ve used a One Spot for a long time, and it works fine with most combinations of pedals. However, that Echoplex does some peculiar stuff in terms of noise combined with specific other pedals. My BYOC Germanium Fuzz Face is wired to accept “normal” power polarity (I can’t remember if it’s center or sleeve positive), but that simple circuit doesn’t seem to “play well with others.” OTOH I can put multiple Tube Screamer circuits, a DS1, and an MXR Badass Distortion all on one daisy chain with no problem. Most pedals take a 9 volt supply. However, others require 18 volts and apparently some take 12 volts (seems very rare). When someone is choosing a power supply it will help to know which of your pedals, if any, require more current (ma) or a higher voltage.

Your power is only as good as the input that’s feeding it. If you have a nice power supply and you plug that into a cheap ikea power STRIP, you’re subject to whatever build quality and noise is applicable with that power STRIP. With a wall-direct connection, you only have to deal with the home or commercial wiring which is much more standardized and generally cleaner than thrown together strips. I would advise against the whole strip approach if possible and go with a wall to well-built extension cord approach if you need more length.

Also make sure the polarity of your supply matches the pedal if it is DC.

I read that volts are the speed of cars going down the highway, and that the amps/current are how closely the cars are spaced

It's really not going to fix the issue imo. The the solution is clear: isolate the power supply to each pedal.

Never had this problem with my solid state amps. Is there something wrong with my tube amp? Or possibly the outlet in my house?

How can you know if the power supplier is truly isolated? I bought a power brick that says "isolated", but it's quite noisy. I use 2 drive pedals, an MXR78 with very little gain (to get some clean-ish boost) and a Wampler Triple Wreck for my tone. I get tons of treble noise no matter what I do, especially if there are more pedals connected (flanger and delay).

Put a meter on continuity or resistance between the grounds of two different outputs. It should read infinity if it's isolated. If your meter beeps or shows very low/zero ohms, then they are definitely not isolated. And lots of cheap power supplies are actually just daisy chains in a pretty box. It's amazing the BS manufacturers get away with. Do your research. I've got a DigiTech Hardwire pedal power supply that's designed to bolt onto a Pedaltrain. It's been rock solid for about 6 years, and my setup is very low noise. I would expect my unit is at the low end compared to a lot of others. Strymons new system looks amazing, and Voodoo Labs has been the industry standard forever.

Current with lithium ion batteries is not a concern, they can put out far more than your giant pedal board will ever need. I don't get why you would go there though. Just get s basic pedal power supply from DigiTech, Voodoo Labs or any of the other reputable companies that make power supplies. These things are cheap, simple, and are designed to be mounted permanently on a pedalboard. They give you isolated outputs, and usually support multiple voltages. Battery banks don't fix the issue unless they are providing you with multiple isolated outputs, which realistically means they're taking DC from the batteries and putting it through a switch mode power supply, meaning the the output circuitry will be identical to a mains unit anyway. So in that case you gain no advantage over a conventional power supply with regards to noise, but are introducing additional points of failure. Get a battery powered unit if you are absolutely set on going eliminating the mains power cord (Why? Your amp still needs mains power right?) If you want to fix your noise issues, just get a proper pedal power supply with multiple isolated outs. Trust me, it fixes the problems and it's reliable. I've had mine for many years and it's still going strong. A lithium battery would have died by now, and I would have had another expense on my hands.

Hi. I have a question. So I ran out of outlets on my isolated power supply. I ran a daisy chain to two pedals, but it was noisy. I had a hiss and what I think was clock noise. To solve that I got a regular household power strip and plugged those three pedals into that with normal wall wart things. The noise stopped. Do cheap power strips have isolated grounds? If so, why are pedal power supplies so expensive?

@seantighe3077

Dustin, I don’t think your problem was isolation but under current, or lack of available current. The daisy chain wasn’t able to provide the current needed to run the two/three(you are not clear on the number) pedals. Giving each one its own wall wart eliminated that deficit of available current. I had a similar problem with a digital delay that was solved in exactly the same way. It got its own psu and the noise went.

All power supplies are isolated from the mains. Your wall wart power supply is isolated. You could fill up your power strip with wall warts, and have no issues. The problem starts when you use a daisy chain between pedals, because then you have two separate ground paths between your pedals, the signal ground and the supply ground. With pedals, don't even worry about mains grounding, it's irrelevant.

I do run 1 24v pedal and have a full donner power supply, go ahead and roast me but it’s what I can do rn lol

I got away with using a non isolated power supply until I started to use the amp’s effects loop. Then the pedals between the guitar and the amp must be isolated power wise from the pedals in the loop.

Noise gates are great and a must in certain styles, but they should compliment an already low noise rig, not cover up problems with a poorly performing rig that's got noise issues. Ways to solve noise issues include: every pedal on it's own isolated supply; keep cables short where possible; good cable management, i.e. no coils and kinks, and keep power cables from running parallel with signal cables, if they must touch they should cross each other rather than run parallel; consider a pedal switcher unit if a lot of pedals are used as this will take unused pedals out of the chain completely. Also 4 cable method > than 2 cable method with noise gates. Put your gain in the loop of the noise gate, that way the gate shuts down the noise, not your guitar.

So a daisy chain to a powerbank battery will behave differently to having a 9v battery in each pedal?

Yes it will. Anyone saying daisy chains off battery banks don't introduce noise doesn't know what they are talking about, and doesn't understand the reason why daisy chains cause problems. Power supplies are ALREADY isolated from mains because the power goes through a step-down transformer before being converted to DC. If there are ripples coming out of your power supply, it's a crappy power supply and that noise has little or nothing to do with your daisy chain. I'm not sure why this comment section is so obsessed with battery banks, but it's like trying to fix an unbalanced tire by putting different fuel in the tank. Get a decent power supply with multiple isolated outputs and you will never regret it. Battery banks exist for a similar reason to cordless power tools. Since your amp needs mains, I don't really see any upsides to a lithium ion battery powering your pedalboard. It's just something that will need replacement in 5 years, and is liable to be flat at the wrong moment.

No matter how I power my flanger pedals, with batteries or even with a dedicated 2amp supply, they are noisy. Is that the nature of flangers?

@jamesm4970

4 жыл бұрын

There's two big reasons flangers (and similar modulation effects - chorus, phaser, etc.) are inherently noisy. The first is because they operate by duplicating the signal out of phase, which additively amplifies the background noise and makes it harder to cancel out through filtering and negative feedback. The second is the LFO. LFOs are difficult to isolate from the rest of the signal to begin with, and thus are noisy, and are constantly changing, and thus are more noticeable. Make the LFO change the phase relationship of the two background noise signals, and you've got a very noticeable noise level. It's the nature of the beast.

A buffer won't use much current. If its transistor based, it's probably less than 100 ma. It may be a little more if it uses an op amp, but I would bet still between 100 and 250 max. Measure the current with a DMM to find out. Limiting daisy chains to two plugs is a great idea. 👍🏻

Yes clock noise, switching noise ect. Digital pedals have all sorts going on, and everything they do is on or off, and every on and off creates noise. Digital pedals tend to have their own switch mode power supplies too, which definitely send noise back out into the supply to mess up a poor unsuspecting dirt pedal. Not much than can be done about a device whose power consumption literally consists of high frequency on/cycles, rather than being linear. Only so much you can filter out.
