The 3 position toggle allows for flexibility in the clipping style and texture. When in FAT mode, the circuit clips in a fat, chewy way. When in LED mode, the clipping becomes stiffer (think of that famous British amp sound that starts with an M that is known for some crunchy textures), with more crunch--this setting is most noticeable at higher gain settings. When the clip switch is in the center position, the natural drive of the opamp is on display. The body control is a unique control to the Supa Cobra. When set low, the pedal remains cleaner, with less boom on the low notes. When the body control is increased, both gain and low-end presence are increased.
The Supa Cobra runs off of a standard, negative center pin 9 volt power supply. Greer Amps’ lifetime warranty covers manufacturing defects and component failure to the original owner, it does not cover misuse or abuse.
