Clandestine Preamp Mod

[DSoda]

Hi everyone,

I'm new to pedalbuilding and I'm enjoying the hobby a lot. I bought myself a few PCBs from the site lately and I'm looking to modify the Clandestine Preamp a bit. Currently it runs one knob, one trimmer, and a toggle switch for the voicing. I'd like to change the toggle switch to a tone knob so I can get sounds in between the set tones.

Any idea how I can do this? Thanks in advance!

I don't doubt Big Monk's assessment one bit.

However, I think it's an interesting exercise that you may be able to learn from and implement in other builds down the road.

Take a look at how Joe Gore implements a simple "tone" control on the little-but-mighty Bazz Fuss:




How this could translate to the Clandestine might be something as simple as this:




You wouldn't even have to breadboard it, just experiment with the PCB-build before you box it by tacking in some wires to the Switch pads, keep the wiring numbers as per the switch with the pot's middle lug connected to the middle switch pad; you may find you prefer lug 3 connected to pad 1 and lug 1 connected to pad 3, but easy-peasy to swap the wires to reverse the rotation.

I'd start with B100k, but you can try anything between B5k and B500k and see what works best for you.


It'll be a fun experiment to learn from and, importantly, reversible for when you chuck that switch back in there instead of the pot. If you want to go crazy experimenting, you could socket C3 & C5 and play around with different sized caps, too, which may make having a tone-pot desirable after all.


Do it for science!

The "laugh"-like was for your first sentence, @Big Monk.

You'd be the last person on earth to stop somebody else from seeking and tweaking tone!

Man, if only I had a completed build for every time I ignored sage & sound advice and tried to tinker only to get a circuit stinker...

Wow, thanks so much!

I may still give the Joe Gore tone control a whirl just "for science" even if I now know it will be a subtle change. Luckily for me, I have 2 Clandestine PCBs.

I plan on doing a 2-in-1 with a silicon fuzz face. Let's see how it goes.
