BOSS DF-2 Super Feedbacker & Distortion

 A useful distortion with secret skills that I got off my old friend Mark Pollard. Also one of my oldest pedals. It’s essentially the same as the workhorse DS1 Distortion but if you hold the pedal down while the effect is on it creates a high harmonic by self oscillating. The harmonic changes every time you change notes and re-press the pedal. I tend to run it in parallel with my clean sound.
