Sound of the Week

Matt Schofield's Overdrive Sound

Mad Professor Supreme is a collaboration with Matt Schofield. Matt wanted to have the best overdrive sounds in one package that is easy to use.

Two Channels

The A channel is based on Mad Professor's Royal Blue Overdrive and the B channel is a new design which gives you a thick dynamic tone with power amp-like dynamics and high headroom.

Different Channels for DIfferent Pickups

Matt uses the A channel with a neck pickup and the B channel with a bridge pickup.
