Rhodes Chroma Polaris

Just noticing that the last post before mine was, well, quite some 
time ago.

Well, it would be nice to chat with fellow owners of the son of 
Chroma. If anyone feels the urge to answer a question or two, here's 
one...on the inside of the polaris, there are 4 different philips 
head pots...does anyone know what each of them is for? I'm assuming 
that they may be for a master tuneing control, or filter 
calibration...I'm just curious though, since I don't want to move one 
if I don't need to.

Cheers,
Byron
