Replace voltage divider chorus depth pot with a toggle switch?

[guitylerham]

Howdy,

I built a Madbean Pork Barrel Chorus and am adapting it to my custom enclosure and need some advice on how I can omit the Depth pot in the circuit and replace with perhaps a 2 or 3-position toggle switch. There is only space for two pots and a small toggle and currently I'm going with Rate and Blend pots.

Here's the section of the schematic:



I've never done this to a pot wired like divider (compared to just a variable resistor). My thinking is, maybe I can leave a 100k resistor in the circuit but somehow switch in/out other resistors to simulate 2 or 3 "tap" points along that 100k. I just can't quite wrap my head around this at the moment. Anyone else do something like this before?

Ah, I just had to do a bit more research but this seems pretty doable. I'll just need to decide what my preset tap points need to be (i.e. max depth, med depth, etc).



I posted too soon! this can be deleted if it's of no use to anyone. Thanks!

Nice work. Simple but effective.

Never mind - was thinking of something else.
