DOD - FX50 Overdrive Preamp (1988, NOT the "B" version) [schematic]
I have a DOD FX50 Overdrive Preamp that I wanted to revive and convert to be relay bypassed. I've searched for the schematic but the only ones I found are either close but is slightly different, or, schematics for the FX50-B, which is significantly different. So, I decided to just trace pedal myself. I have my traced schematic, the pic of the front of the board with component numbers added, and the flipped pic of the trace side of the board. They're all in here in case it could be of use to someone: https://www.dropbox.com/sh/8i99gntvkg5z ... w54Za?dl=0.

Since you mentioned both, and I have both, here's their guts, side by side.
'84 FX50---'89 FX50B;
'84 FX50---'89 FX50B;
Thanks for the input, guys. Mine looks more like the 1984 with the TL022CP. I assumed it was an '88 based on the sticker on the back. In retrospect, I did buy it before 1988. Maybe around '86~'87. Looks like the opamp is the only difference between '84 & '88.
