Guitar pot with built in Boost?

I’m not sure but most pots in guitars are 250k or 500k. Maybe add the boost with an additional pot.

 

It’s possible if you can find a 5k pot with a push/pull DPDT switch built into it.

If you can find a 5k with DPDT then you can use it as your true bypass and boost control.

Put a stereo jack on the input jack of the guitar to supply the battery negative to the circuit when a patch cord is plugged in. There’s your power switch.

Anything is possible but you need that DPDT 5k pot to make things easy.

 

I just did a quick check. Bourne makes a 5k with push/pull DPDT. I’m not sure who carries them. Digikey, who I buy from don’t have any in stock but they list them for about $5 each and have a Standard backorder time of 18 weeks. Since we know they’re out there, I’m sure someone has them.

EDIT: That 5k pot isn't going to be useful for anything else while the boost is bypassed because as @sirbergersworth mentioned above, guitar circuits are usually 250k or 500k.

 

Why not install a standard 5K pot and a mini DPDT switch that activates the boost and the pot? Is it because you don't want to drill an additional hole?

 

Instead of the PCB you have will this do what you want?
It's cheap enough.

Yeah. That is cool. I’d go with this one if I were looking to add some active gain to a guitar. The price is a no brainer.

 

I build these for all my guitars. Work great for a clean boost.

 

you could use a 250k/500k switching pot as one of the guitars vol/tone controls. the switching function of the pot activates the boost, but the boost itself is set-and-forget inside the guitar, with no external control.

 

That's how the one I showed is. Boost is adjusted via a pot on the board and the external pot is just for guitar volume and switching the boost on.

 

Emg SPC Midboost Use it in all my guitars. It can really push the amp over the edge and whith clean it gives the extra boom. Works perfect with passive pups too.

Durk,

What kind of circuit is that? I see it is designed by PedalPCB but I do not see it on their website. Is it commercially available?

 

Torres Engineering used to sell stuff like that
Some of it was pretty cool, too

 

Sorry for the late reply. I am friends with him and he did a special run of these for me a few years back. it is not a copy of anything else available.

 

If I'm not mistaken, that's Super Hard On or Earth Quaker Devices Black Eye. I've been planning to build one of those for a while. Got all 12 parts put aside and a piece of veroboard. I just haven't warmed up the soldering iron to actually build it. That's a nice little circuit board.

Here's the one I'll build:
