Dr Boogie gain pots for less gain?

[ghostsauce]

Hey guys been a long time hope you all are doing well

I've built another dr boogie cause i love these things, and this time i went with additional gain/volume pots for a pseudo second channel.. and now i am looking at fine tuning the gain pots because the 1mA is just an insane amount of gain and i want about 1/4 to 1/3 of it to make the knob more useable. I tried a 500k and it still has far too much, so i'm about to put in an order for a few different values and was wondering if anybody here has used 100k's or less in these with any luck?

Also look at this beautiful thing. Left side is the boogie, right side is a rog tonemender. it's one hell of a 3 channel preamp

It's a voltage divider, the value of the pot has little to do with how much signal it attenuates unless you go to extremes and approach the source impedance.
Stick a resistor between input and pin 3 of the pot. https://www.build-electronic-circuits.com/voltage-divider/

I'll give it a shot but I've come across people mentioning this, won't it accomplish the same thing as using a different pot value except also destroy the log taper?

Not at all. Did you read the article?
Having refreshed my memory of the schematic, there's already such a pre-attenuation resistor, though bypassed by C6. It means the source Z is significant, for low frequencies at least.

Are we talking about current gain..??

Scratch that, it was just poorly biased. now the gain on tap is pretty much all useable so there's no need to adjust the pots, but i appreciate the input. thanks folks

Are we talking abour current gain..??

i meant the 1m audio taper pot not amps, haha

One milliohm?!

i think the MA stands for mega awesome iirc
