I have been looking at the schematics for the cMoy and have to ask, why place the volume pot infront of the amp? Why not place it after it? Cause wouldn't a volume pot placed before it act exaclty the same as the sources volume pot?

--
Side question, has anyone used photo flash capaciters in a cMoy? I have about 90 flash circuits from various disposiable cameras around, and I could salvage them for a couple of cMoys.

This would have advantages WRT noise, however it would give you an output impedance that depends on the volume setting, with high values in the middle of the pot's range.

Your pot cannot drive that much current and you may fry it.

Another reason is if you're driving the amp with very "hot" output (i.e., high output level), if your volume pot is not at the input side, your amp could be driven to clipping. A volume pot at the input side will prevent that from happening simply by turning down the volume.

Well, that answers that. Thank you.
