A unique take on the clean boost
Unlike conventional boost pedals that simply increase output level, the Fumble uses a carefully voiced JFET preamp circuit to enhance your guitar's natural character while providing exceptional flexibility. The distinctive Input control simultaneously adjusts bass content and input gain, allowing you to move seamlessly from a tighter, leaner response to a fuller, louder sound. This unusual approach creates a remarkably dynamic feel that responds naturally to different guitars, amplifiers, and playing styles while maintaining impressive clarity throughout the control's entire range.
Ideal for stacking and amp enhancement
The Fumble excels as the first pedal in your signal chain, adding definition and polish before your favourite overdrives and distortion pedals. It can tighten low frequencies before higher-gain effects, helping chords remain articulate while giving lead lines extra focus and sustain. It is equally effective pushing an already driven amplifier, adding volume, presence, and harmonic richness without masking your amplifier's own voice. Positioned later in the chain, it also works as a transparent solo boost that helps your playing stand out without dramatically changing your overall tone.
Simple controls, exceptional results
With only two controls, the Fumble is quick to understand while offering far more tonal flexibility than its straightforward appearance suggests. The Output control adjusts the pedal's overall level, while the unique Input control lets you shape both gain and bass response together for a remarkably broad range of clean boost sounds. True bypass switching preserves your original tone when the pedal is disengaged, making the Fumble equally suitable as an always-on tone enhancer or a dedicated performance boost whenever you need extra presence.
Built with JHS quality
Hand assembled in Kansas City, the Fumble reflects JHS Pedals' reputation for thoughtful design and dependable construction. Its compact enclosure occupies minimal pedalboard space while consuming just 5mA from a standard 9V centre-negative power supply. Whether you're looking to enhance your clean tone, improve the response of your drive pedals, or simply discover a different approach to boosting your amplifier, the Fumble delivers a distinctive voice that's destined to become one of the most important links in your signal chain.
