Fumble is a compact JFET-based clean boost and preamp inspired by the legendary Dumble BBC-1 circuit. With only two controls and true bypass, it delivers a full, dynamic, and highly musical amplification that enhances both guitars, pedals, and amplifiers without unnecessarily coloring the fundamental sound.

Controls

• Output – adjusts the output level.
• Input – a unique control that simultaneously reduces input gain and bass response. High settings provide maximum fullness and level, while lower settings give a tighter and more focused response.

Applications

• As a buffer and clean boost first in the signal chain
• To drive overdrive pedals harder and more dynamically
• To boost an already overdriven tube amplifier
• As a volume boost for solos and highlighted sections

Fumble is not an overdrive pedal, but a transparent JFET preamp that adds clarity, headroom, and articulation. The simple operation and distinctive Input control make it an effective tool for guitarists who want more of the good sound they already have.
