Picked this up used yesterday. Pretty dang nice sounding, overall.

Some notes:
-- IC is a TL062C
-- The 3 center pots (tone controls) all measure ~29K
-- The 2 outside pots (volume and gain) measure ~94K
-- The small electrolytic caps are both 10uF, and the large one is 100uF
-- The lone through-hole film cap is labeled as 3.9nF (392J)

Here's a ZIP of the full-resolution images for those who are interested:

Haha, different strokes for different folks! Granted, I've not played through it enough to get a complete picture.
