JHS Pedals - Fumble

The JHS Pedals Fumble was born out of a design error that ultimately revealed a particularly interesting circuit: a BBC-1-inspired JFET preamp combined with the Dumble sound. Its role isn’t to saturate your sound, but to shape its response and level to make your guitar sound more present and defined. Placed in the right spot in your signal chain, it can become that little extra something you end up leaving switched on all the time.

The Output control adjusts the overall volume and allows you to boost the signal to the amp or other pedals. The Input control is more than just a simple gain control: by turning it anti-clockwise, you gradually reduce the bass and input level to achieve a tighter, more refined attack; turning it to the right preserves a fuller, more powerful sound. This unique feature makes it a useful tool for boosting an overdrive, adding articulation to an already overdriven amp, or boosting the volume at the end of your signal chain for passages that need to stand out.

With its JFET boost circuit and true bypass switching, the Fumble is easy to integrate into your pedalboard. It can act as a buffer and clean boost at the start of your signal chain, but can also thicken the signal before an overdrive or provide support for a solo thanks to its high output level. Assembled in Kansas City, Missouri, it runs on a centre-negative 9 V DC power supply and draws just 5 mA.
