Title: Service Manual/Schematic needed: Roland CH-40 Chorus c.1984
Post by: willpirkle on June 11, 2023, 10:51:06 PM
I'm looking for the CH-40 + chorus service manual. I have the original CH20/40/60 service manual from 1979 but it doesn't cover the "chorus" variant, which appears to have been a later version with a fixed chorus, and differing also in the rear panel inputs/outputs.

TIA - Will
