Sound of the Week

Blackface Fender in a Pedal

Mad Professor Super Black gives you the Blackface-era Fender amp sound in a pedal.

Amp Circuitry inside

The whole circuitry of a vintage Fender amp has been replicated inside the Super Black. Due to this, the Super Black does not just sound like an amp, but also acts like one.

Sweet Honey on the Other Side

The second channel of the pedal features the Sweet Honey Overdrive, the best-selling pedal in the Mad Professor lineup.
