This was great - thanks for sharing. I wanna try this with some old Marshall combos I have laying about..

Good idea. Got some 15W amps, that are pretty different. My Samick has reverb. My Behringer has those setting switches. My RockTile has a speaker that loves distorting. And my large Solton speaker is a nice 1980 speaker. Making combinations is fun. Simple connectors can do the job, but adding audio connectors (and audio cable plugs) enables you to plug in the speaker you want.

This was very helpful. Thank you!

Great video man! Thanks!

Cool video, I'm gonna try this with a Fender champion into an old fender bandmaster cab front he 60s in a few months.

Nice. Thanks for sharing.

This is just what I've been looking for for my mini amps!

Hi Dave, Awesome Video and delivery. Hey, can you let me know are the added Part#'s to help me modify one of my small practice amps? It would actually by nice to have the Amp Speaker be Live, along with the External Spkr so that I can begin using the external one as a Monitoring speaker during my live performances! Thanks Again!

Dude- no idea you had a channel. Dan, Sid Vegas. Turning a fend champ 30dsp combo into a head, saw guys do it on here, it will run a 4x12..insane, i already tried it. B lookin forward to ur vids

Dave, thank you. This is exactly what I want to do with my VOX AD30 VT. Question: This is a guitar amp but I want to try using it with my bass guitar. I wish to build a cab for a 15 inch woofer and use my Vox to drive it. Since I can’t play both guitars at the same time I thought why have two amps? So is this a good idea or bad? Will my vox happily act as a guitar and a bass amp as long as I use appropriate speakers or do I need a bass amp designed to drive a woofer? Again, thanks for your videos, I am learning lots. 👍

Awesome Video, quick question can I utilise both my Combos original speaker and plug it in to a 2x12 so in effect having a 3x12? I have a 50watt amp where the built in speaker is 16omh and my 2x12 cab is 8omh

How do you know what size resistor to use? Good video btw.

LOVE IT , but i'm interested in adding speakers to a a 2 x 12 like to add 2 more in a 2nd cab to make a total of 4 speakers, would that work?

CalitranoN it will work only if your output is set up to take more speakers. Whenever you add speakers, you’re changing the impedance. If you have two speakers now and they equal 8 ohms, and you add two more speakers that are 8 ohms, you’re lowering the overall impedance to 4 ohms of the speakers are in parallel. That’s not a good thing, especially if your amp is a tube amp. I would advise against doing the mod in that fashion if you’re not sure how your amp is set up. What kind of amp do you have?

Pretty confident on soldering those speaker wires without protection of the cone....lol. I would have dripped solder through the cone...

question! if you add the speaker input on the amp does the sound only play on the cab or both ?

Hey Dave. Nice job there. Is it possible to use my Fender mustang's GT100 celestion speaker (4ohm) as cabinet and connect it with a tube head?

As long as the impedance for the head is 4 ohms, that's fine. In fact, people do that kind of thing all the time. But if the impedance for the head is higher, don't do it. You could blow your OT, or your tubes, diodes, etc...

can you help me source a Jack or item # to get one

ok so when you have an external cab plugged in it will use the external cab, but if you unplugged the cable at the CAB side. because you have resistor in place it will not burn out the amp the 220 ohm load will keep everything good to go. so you can change CAB's or input channels on the line out?

@davetriestofixstuff4744

3 жыл бұрын

Yes, the resister will help to protect the OT. But the since the resistor is only 2 or 3 watts, it’s not going to protect it indefinitely, especially if the volume is up and a signal is being passed. The resistor will burn up eventually if that happens.

Can I plug headphones into that jack? My amp already has a line out but it doesn't have a headphones out. If so, I would re wire it this way so that it mutes the amp speaker, since currently, they stay on when using the line out. Thanks!

@davetriestofixstuff4744

No, this won’t work for headphones. The wiring would need to be different since the power could easily blow your headphones, and the impedance of your headphones may not be right to keep from damaging the amp. I would not suggest using headphones with this mod. Sorry.

Awesome video man. Very helpful.

ian Randant hi. I’m not thinking that this type of mod would work for that. Normally, a power in jack on an amp is allowing another pre-amp signal to be directly connect to the power amp of the amplifier. But the signal coming out of a jack with this type of mod is a fully amplified signal, not a pre-amp signal. It would completely overload your Nashville, not to mention possibly screw up your Envoy due to the impedance mismatch. Sorry, but I wouldn’t suggest doing it. Thanks for watching though!

This is exactly perfect for DAWs. Think less "EXTERNAL SPEAKER JACK" and more "AMP SILENCER/ LINE-OUT TO NEW SOURCE" jack. ...Or as just a "BYPASS/OUT" jack. It kills the combo's speaker while automatically redirecting into a hookup signal source link (LINE-OUT) when plugged in so you're getting only what you want through and bypassing what you don't while redirecting as a hookup for live cabs or software recording using headphones or monitors or ran into a combo... which you can then mic if ya want.

The JDX48 works between a Amp head and Speaker, so guess something could be put together like this using your speaker jack idea.

Dave, is the resistor connected in parallel and always in the circuit when the external cable is plugged in regardless of whether or not a speaker is at the end of the cable? Meaning the resistor will alway be in the circuit when the external cable is plugged in - with or without speaker on other end. Which lowers the impedance and diverts amperage from the speaker?

@davetriestofixstuff4744

Жыл бұрын

Yes, the resistor is in parallel with whatever speaker is hooked up. But the resistor’s effect on the impedance is nominal. A 220 ohm resistor in parallel with an 8 ohm speaker only lowers the overall impedance to around 7.72 ohms. It won’t have a negative effect on the OT or power tubes if that’s what you’re running.

I'm trying to locate that style 1/4" input jack. Is there a specific name for that type? I like this jack vs having to add a switch and a standard 1/4" input jack.

Feasibly, you could, but I wouldn’t advise it. If you did, you would have to monitor the volume to keep it very low. Or you could install a resister in series with the jack to lower the signal to a lower level. Otherwise you’re more likely to blow out your headphones or your eardrums or both.

I have a question can you use PA speakers, external cab for electric guitar or acoustic?

You can use pretty much any modern style speakers provided they have an impedance that matches the output of your amp. But I can’t comment on the tone of those speaker as they weren’t made for guitar. PA speakers may be decent for acoustic though, since that’s voiced differently than an electric. Good luck!

It should work fine with the Pathfinder. As mentioned in the video, just make sure the impedance of the external speaker is the same as the one in the amp cabinet. It’s not a capacitor that’s put across the tabs, it’s a 3 watt resistor with around a 200-300 ohm value. Good luck!

I'm dubious about the no load protector resistor ? I had a Traynor BaseMaster 50 watt tube head, I used for many years in a band as a lead guitar amp. We constantly would leave equipment on and unplugged from home made speaker cabs, of which we knew nothing about various ohms, and go for beers ( we didn't know any better) but... it work flawlessly for 30+ years. Never had an issues or changed any tubes, ever. Hmmm...

That’s a great point. I have aTraynor Bassmaster 50 myself (to be featured in an upcoming video), and those are in push pull configuration.

I’ll be sure to go into that a bit more in the upcoming video.
