In the current JustPedals catalogue, Mad Professor is represented by Overdrive Pedals and Wah & Filter Pedals. Current listings include 1 Overdrive PCB, Snow White Auto Wah PCB and Evolution Orange Underdrive PCB. That makes the range relevant to players looking for drive, gain and clipping. Check each model for its exact circuit or processing platform, controls, power requirements and connections, particularly where the catalogue includes both pedals and supporting gear.
