To enhance its performance, the circuit includes thoughtful modifications. Smoothing capacitors have been added to eliminate high frequency oscillation at higher gain settings. The output stage has been fine tuned with different resistor values to provide a more pleasing volume and noise threshold. Additionally, a filter capacitor has been integrated into the power supply input to minimise power related noise.

One standout feature of the Stumpbox Pedals Get Fuzzed Silver Knob is its wide ranging bias control. This control allows musicians to fine tune their fuzz tone to their preference, providing a high level of customisation.

Every Stumpbox Pedal is built and meticulously tested by the founder, Andy Banks. Only carefully selected, high quality components are used, ensuring excellent tone and minimal noise. The pedal features Gorva footswitches, Alpha pots, Bourns trimpots, Lumberg input/output jacks, a Cliff DC jack, Wurth & WIMA capacitors, CDIL BC183L & BC182B transistors, an Onsemi diode, and a Hammond enclosure that is professionally drilled for precision.

In summary, the Stumpbox Pedals Get Fuzzed Silver Knob offers a glorious and dynamic fuzz experience. It delivers all the fuzz madness you desire while also responding beautifully to your guitar's volume knob. Whether you're recording in the studio or performing live on stage, this low noise fuzz pedal is sure to impress with its harmonically rich tones.

What's In The Name?

Curious about the origins of the company's name? "Stump" in Stumpbox is an homage to the esteemed Stump Tailed Macaques, also known as "Stumpies," who reside at Monkey World in Dorset. Monkey World is a remarkable primate rescue center established in 1987 by the late Jim Cronin and Jeremy Keeling. Today, it is expertly managed by Jim's wife, Alison, and her exceptional team. The center is home to over 250 rescued and endangered apes and monkeys from various parts of the world, including the largest group of chimpanzees outside of Africa. Monkey World's daily operations are featured in the highly popular television show "Monkey Life."
