Vibrato
Seppuku Fx Mind Warp
Schematic, trace and info avaiable at FSB. Note that there is a cap value missing across pin 11 and 12 at the PT2399. There is a 10nF cap across pin 9 and 10 so a close value to that should work. Also, lug pot numberings isn’t marked on iether of the schematics so lug numbering … Read more
