Arduino replacement for the digital innards of the original SansAmp PSA-1 guitar pre-amplifier.
The ROM in my SansAmp got corrupted, so I built this contraption from an Arduino Pro Mini and an OLED display. It plugs into the PLCC socket, replacing the MC68HC11 processor.
The OLED mod is reversible, as the original 7-segment display is just bent down (the glue broke on my unit anyway).
- MIDI support
- Proper PCB
