2 channels contain almost any overdrive or distortion sound you could ever want. "Jekyll" channel sounds like the original TS808 and even uses the JRC4558 op-amp. "Hyde" channel goes from blues to metal and everything in between. EQ knob on Hyde changes from a flat EQ to a wild scooped mids sound, while the Sharp/Blunt switch allows you to get a very bright or more compressed sound. Combine the channels for hot blues, raging rock, or molten metal leads!
