EHX 4 Knob Deluxe Octave Multiplexer Schematic?

Any schematics out there for the 4 knob EHX Deluxe Octave Multiplexer? Looking for the 1325C version, not the 5950 version which is readily available. They seem quite different.

Never mind. There was enough clues on the 5 knob schematic to help me repair the pedal.

Did anyone ever adapt this for LM13600/13700?

Hey guys,

I have a 4 knobber and it has a weird problem. the octave component of the signal is getting squashed at the attack and then releases it moments later sounding like a quasi delay effect. any ideas what the issue could be?
