DOD FX75 Flanger Guitar Effect Pedal
This is the circuit diagram of DOD FX75 Flanger guitar effect pedal. The circuit drawn by Fabian P. Hartery.

Featuring a Width control and two output jacks, the FX75 was much more versatile than its predecessor, but the flanging effect it could provide was still not very intense. That said, chorus-like washes of flange can be easily dialed in, and the FX75 can sound quite musical.
