Master Volume Celsius Mod

[anevilspar7an]

I'm going to be building a highly modified Celsius + Cepheid combo build. One of those mods is a master volume on the Celsius preamp before going into the chorus, I read that someone just put an A500K at the end of the output buffer after R11. It seems a bit high, A100K sounds more reasonable. I would like to know if this is the correct way to go about it from someone with more experience.

Here's where I'd start the monkey-shines on a breadboard...

Replace R14 with an A5k pot. R13 feeds the pot's lug-3, lug-2 is the new OUT, and lug-1 to ground.


Could also try A10k, A25k, A50k, A100k, but I'd start with A5k.



Further monkeying with gain (real gain, not the input-attenuator pot mislabelled as "GAIN"...

GAIN = R10 ... Could stick a B500k pot there wired as a rheostat, replacing R10, but in series with a 47k resistor. You'd get a bit more gain 547k and be able to lower it to almost buffer status.


More monkey-shines...
Replace R9 100k with an A100k pot, just like the R14 swap. Signal from C4 feeding the pot's lug3, output lug2 goes to the HI/LO-switch and lug1 to ground.

Caveat emptor — I've no idea about what I just said to do.
