Clipping = Distortion, and for many years we’ve only been offered two clipping choices: Soft-Clipped or Hard-Clipped.
Soft-Clipped pedals include Tube Screamers, Fulldrive2, OD-1, Zendrive, etc, which get their distortion by using diodes placed in the feedback loop of their Opamp. This type of clipping is generally favored by the folks wanting a cleaner, more compressed, low-to-medium gained Overdrive sound. The other choice we have are Hard-Clipped pedals like the RAT, Distortion+, Boss DS-1, etc. These pedals create distortion using diodes tied to ground or, unique to the Fulltone OCDv2, Mosfets that are tied to the half-way point between 9volt and ground (Vref) offering a more natural sounding distortion, one that emulates the SAG (feel) of an amp’s tube rectifier..

The original PlimSoul is the only pedal to offer both Soft & Hard clipping with separate control over each. I designed the PlimSoul’s unique, independent dual-stage clipping circuit to replicate not only the sound, but the feel of a tube amp with its subtleties and complexities.

The original PlimSoul was a great first step, but the PlimSoul mkII offers significant improvements over it:
Input Impedance increased from 500k to 700K+ ohms for even better interaction with guitar’s Volume knob.
