Yamaha FL-01 Flanger with power supply mod. 1980s

Yamaha Flanger FL-01 in Good condition.

Innovative, well-built 1980s flanger pedal known for its ability to achieve a full feedback loop, producing synthesizer-like, self-oscillating sounds. It excels at retaining low-end frequencies, preventing bass loss common in other flangers. Key features include solid metal construction, a unique Manual/Feedback control system for extreme effects, and a compact design. While not widely known, it is considered a favorite among those who have used it for its extreme sonic range and robust performance

The pedal has been modded in order to be used with a 9V DC center negative 2.1mm barrel power supply (same as the super common Boss type). It cannot be used anymore with a battery.
