Bear with me a sec.
Grr.
So I've got a distortion pedal. I'd like to have 2 volume controls that you can switch between, kinda working like amp channels I guess. Set one quiet, set one loud and it's sort of an inbuilt boost (almost). I'll also be using a bi-color red/green LED which I've drawn up, but I can't figure out the easiest/safest way to make the 2 pots switch seamlessly without popping etc.
I started off with this:
But was informed that the volumes would be interactive.
Then I thought about a 3pdt. 2 poles for the switches, 1 pole for the LED (wiring not shown here sorry), like this:
Then I heard from PedalPCB about just switching the outputs of lug 2 and leaving the inputs conjoined, like this using a DPDT (again the other pole is for the LEDs):
With the pin at the end there being the output pad.
The last method seems the easiest and most painless as one consideration mentioned with the middle method (switch poles before and after the pots) was a dropout as the switch is a break before make style so there'd be no anything for a split second before the connection sorts itself out.
This is going in a distortion pedal btw. Nothing amazingly fancy. Some clipping stages, then an active tone stack, then out through a 10uf cap into the volume pot as a regular voltage divider. I'm just trying to work out how to add a silent, instant switch where each pot is isolated from the other.
Any ideas?
