JHS Pedals The Fumble JFET Clean Boost Pedal

The JHS Pedals The Fumble is a compact JFET clean boost built for players who want more clarity, touch sensitivity, and presence — without adding color, grit, or gain. This is not an overdrive or high-gain pedal. It is a transparent, musical boost designed to enhance what is already there.

A Unique JFET Clean Boost

The Fumble is rooted in the Dumble BBC-1 / FET-style circuit — a design connected to the clean section of JHS's own NOTADÜMBLË V1 project. That lineage traces back to a vintage Barcus Berry acoustic preamp that eventually found its way into the legendary Dumble FET sound. The result is a boost with a character that is open, articulate, and responsive to your playing dynamics.

Controls

• Input: Attenuates bass and input gain together — roll back for a tighter, focused response or open it up for a fuller, more present sound
• Output: Master volume control for overall boost level
