ok well this schematic is for the mace/deuce but its the same as the peavey classic. the top right section is the phase part and just below it is the color and rate knobe middle right. it looks like it has six ca3094 ota op trans amps . i am a little confused how the color pot works its coming after the post gain. very confused on how to seperate this circuit for stand alone. anyway here are the pics of the schematic.
