JHS PEDALS

JHS Fumble Clean Boost Pedal

The JHS Fumble is a unique JFET clean boost pedal inspired by a rare preamp circuit associated with the legendary Dumble FET sound. Simple yet highly effective, the Fumble enhances your tone with increased clarity, articulation, and musical boost without coloring your core sound.

Featuring just two controls, the Fumble is easy to dial in. The Output control serves as a master volume, while the unique Input control simultaneously adjusts input gain and bass response. Turning the Input control down tightens the low end and reduces gain, while turning it up delivers a fuller, louder, and more dynamic response.

Sound & Controls

The Fumble excels as an always-on tone enhancer, a front-end boost for overdrive pedals, a way to push an already-driven amplifier, or as a solo boost at the end of your signal chain. Its responsive JFET circuitry provides a clear, dynamic feel that works equally well with clean and driven tones.
