GGG Ross Clone Volume Problem

[jmclaren]

I just built a Ross compressor clone using a General Guitar Gadgets circuit board.  The layout calls for a 50k audio pot for the level control.  I had a a 100k audio pot on hand and used it instead.  The compressor works fine, accept that I don't get unity gain untill the volume pot is turned almost all the way up.  Could the pot value difference cause this, or should I be looking for a different problem?

100k will work, and is working. The output of a Ross is pretty near unity as is. To eke a little more out, replace the 10k resistor in series with the output pot with a jumper and that should give you about 10% more using a 100k level pot (which is probably just barely enough to even notice, but still - better than nothing right? )

Thanks for the response, Jay. Would swapping in a 50k pot make a difference?
