The "Mad Drive" takes all of the classic gutsy mid-heavy "Tube Screamer" overdrive tones and adds two more completely different voicings with using the classic JRC 4558 chip

OD-10 has three modes:
"Normal" is the old-school Tube Screamer thing...lots of thick searing mids, BIG bottom end and a smooth crunchy high end.
"Bright" is a thicker, fuller, warmer version of this tone....great for smaller amps- a GODSEND with a modelling or solid state amp.
"Warm" is a leaner, more modern Tube Screamer sound- this is especially good with richer sounding amps
