NYC Guitar Tone
The Super 72 is a high gain overdrive pedal, offering a controlled tight bottom end and a rich harmonic saturation, allowing every note to be heard. For the lover of a big muff pie (without the jet taking off noise) the Super 72 delivers a much sweeter harmonic tone, a usable full sweeping tone control and a truer tube overdrive sound. There is no control for the amount of drive the volume just controls the output level. The harmonic feedback widow allows a the possibility of infinite sustain or a singing feedback that maintains the realm of useability.
The old mirrored ones that Billy Corgan uses are called "Bloody Fingers" he gave it the name on some Youtube videos so the name stuck.
