@@obsoletecd-rom good question! First of all how much do you know about electricity and circuit design? If nothing I would try to gain a cursory understanding of that first. Google ohms law and you should find a ton of resources. After that I’d look up op amps and treat them like a black box. Don’t worry about why they work just how. Research circuit transfer functions. What that means is a certain voltage(or current) in will have a corresponding voltage out. We refer to this as gain. Since you’re building guitar pedals it’s important to understand the frequency side of things. (Note this can get complex so if you don’t want to learn it I understand). You can google capacitors and frequency response. Basically frequency responses are derived from transfer functions (Gain equations). You can think of these the same way except certain frequencies are boosted while others are cut (usually). For this google filters- low pass, band pass, and high pass. If you don’t want to learn this just google filters and figure out how to construct them. Now that you’re here you’ll probably want to research FETS and diodes. With these circuit elements you can build a hell of a lot of pedals. Once you’ve done all that you’ll have a pretty good idea of what to learn next. It looks like a lot because it is. I’ve spent years learning this stuff, don’t get frustrated if it takes a while. Just learn step by step and you’ll enrich your understanding greatly.

Thank you for this brilliant description Brian, it's nice to know how overdrives are configured, and the difference in the output signal. I like the idea of talking through the circuitry of effects pedals giving an insight into the function of the stages. The op-amp was the best in my opinion.

Would love to see these types of videos often! Love learning the terminology, as well as the interplay between pickups (type, distance...), volume control on guitar, and the settings of each part of a pedal. Plus, I am a home electronics geek. So it is great that you made them on a breadboard! MOSFET, for me!

Your videos and your products are top notch! You’re the Lindy Fralin of the pedal world. Thanks for sharing this info!

Thanks! It's nice to have a clue about things like this, and your videos make it more fun than reading a wiki or something.

Really Really great video. You’ve a great way of explaining pedal innards in layman’s terms. I learned soooo much from this video. Amazing to see you on the Guitarist Ireland forum from time to time. A real treat.

TY Mr. Wampler! It needed almost 40 years to find my Gain/Overdrive pedal and style. I tried tons of pedals but none survived on my board. Till i found some with the "hint of clean signal". Right now i use a King of Tone and a Morning Glory. That's more than enough for my music genre and i'm totally happy.

Thank you for doing these videos. Very informative

Mr Wampler schoolin again! Thanks Brian! Needed the refresher! :)

Dude, I could geek out with you for at least 1-2 hours before my head exploded. Love your work!

Great video as always. Big big thank you!

That was great. I like these kind of videos. Keep them coming. They're edumacating magicry. Also...can't wait for my Belle overdrive to show up this week. That should answer my question on which circuit I liked the best. Cheers!

Love this vid. J-fet and mosfet are my favs in this comparison I’d LOVE to see another dist-circuit comparison but with other consistent EQs preceding the gain stages (like cutting the bass significantly before clipping etc) and the impact on it all 👍👍 Cheers

Brilliant video. Please do more like this. Very helpful.

Nice to see you again Brian :) Great video. The lesson here seems to be "don't turn the gain all the way up". Except when it's single coils into non-inverting op amp.

Wampler pedals usually have plenty of low end. I think that fullness is what helped it win. I honestly prefer it over a real klon.

I struggled with them so much because I am mainly a home player, which is quite common really, but I eventually found if I bought one and initially wasn’t crazy about it, it was just because of not having the volume knob up high enough. Once I moved the volume up just a little more, it brought them to life. I helped a couple buddies out with it, move that knob up one and a half more! I just finally bought a Tumnus classic, and I absolutely love what it can do. It’s just a great little pedal, thanks Bryan!

This was really useful. I had to reevaluate things that I thought I knew for some favorite overdrive sounds.

Awesomeness as always. Thanks for the insights.

Good to hear from you again.

I lean towards op amp overdrives, mosfet sometimes. It would be great to see a video on inverting vs non-inverting op amps!! Thanks for the great & intuitive vid, sir!

I really liked the op amp in the low gain. I like hearing the subtle clean in there!

I like them all but I definitely prefer the MOSFET. Thanks, this was super helpful!

This is killer content dude! When I was a wee young lad I got a TS for Christmas and HATED it. I thought it was broken because I could still hear the clean signal (not a very complimentary sound into a sterile clean Crate amp). It was only after discovering tube amps and running them a bit hot did I awaken to the majesty of these types of drives.

Thank you for this very informative video.

Wow. The Mosfet is creamy! My favorite. Thanks for sharing this, Brian.

Thank you and your good company sir!

Thanks for the informative video! I like the sound of the JFET the best.

Main thing for all three OD types is that I liked all of them better in the mid settings - that way there's nice crunch, but still a lot of chime. I like hearing those chewy legato phrases along with the ringing chord thing going on. Thanks for sharing Dr. Wampler - my wife can attest that I have far too many of your pedals strewn about my music room :)

Here is where I come for real knowledge of a particular circuit, etc. I use three of your pedals,( All I need). Save for my Fulltone OCD. ...You are the man Mr. Wampler.

Thank you, Wampcat! Thank you, Wampcat! Thank you, Wampcat! I am rebuilding my studio after major theft, and really needed to hear all these! (And I am an EE, so I heard every word meaning.)

Nice demo and explanation, Brian. Who knew I like non inverting op amps? I do, now.

Outstanding video ‼️😎🔥🎸

This was SO helpful!

Great explanation thanks .

I liked the op-amp best but I’m also a huge Telecaster fan & your Tele sounded great with that circuit. Thanks for this educational video. For me, this definitely cleared up some confusion I had. Lastly, I bought the Belle & I love it! It replaced a Blues Breaker type pedal on my board because it does the flat EQ thing better. Great job!

I liked the Mosfets best in these examples. Sounded great on it's own and handled the boost well too.

that was educational - thanks Brian !!!

This was a fun watch, great video! I'm using FET based overdrives made to sound like classic amps. I boost them with a MOSFET booster. It's all stuff I built from DIY circuit boards. My old Peavey Classic 50/50 amp does not have a preamp to speak of, so it really takes advantage of the fet drives with real tone stacks in them. I have noticed that the mosfet circuits take a full range boost better than the jfet's but the jfets love a top end boost. My board has a Sunn Model T and a 70's Hiwatt preamp pedal at the moment, building a Bandmaster and Ampeg one soon.

Great video! All 3 of those types of ODs are on my board. Wampler pedals are high quality!

Whatever circuit the Belle is!!! That’s my all time favorite. It is an incredible pedal and thank you for building it! I’ve sold off quite a few other Pedals now and I won’t miss them!
