Provides an additional control for fine-tuning gain.

Independent shopping perspective
Marshall’s JCM800 pedal brings the JCM800 amp’s gain-focused voice to a stompbox format. It covers crunchy rhythm work through to more forceful lead settings, with rotary controls for shaping the result and a Sensitivity control for further gain adjustment. The compact black-and-gold enclosure keeps that JCM800-inspired sound within reach on a pedalboard, so you can make changes from the floor rather than relying on a full amplifier setup.
