I haven't yet fully traced the circuit, but I'm about 75% done and at this stage it is looking like it's a Boss CS-2 with a blend mod to mix the dry and compressed signal.
IC is LM13700N, FETs are J201 and transistors are 2N3904.

Confirmed: This is a Boss CS-2 clone (using a LM13700N instead of BA662A), with adjustable blend of compressed/dry signal.

So it's half of LM13700 here witout buffer and diode-bias, so can we use CA3080 here? Using less space..

I miss values of rezistors in the scheme. Could you please post them?
Also, do you have this scheme and/or pcb design available for download in format for Eagle or KiCad?
Thank you.

Why don't you do some of the work yourself? Gut shots are available and pcb is numbered.
