PedalPCB Fumble (JHS Fumble Boost Clone) – Powder-Coated Black Prismatic CosmosOverview

Looking for that mythical, ultra-transparent clean boost without paying thousands on the collector's market? This is a meticulously crafted PedalPCB Fumble, a direct and faithful recreation of the legendary, short-lived JHS Fumble Boost(originally built as a tribute to the iconic Dumble amp clean channel).

Housed in a stunning, heavy-duty Black Prismatic Cosmos powder-coated enclosure, this pedal looks like a galaxy on your board and sounds like absolute magic.

The Tone: What does it do?

The Fumble isn't just a volume knob; it’s an absolute tone-sweetener. It provides a massive amount of clean headroom, adding a glassy, high-definition clarity, touch-sensitive dynamics, and a subtle harmonic richness to your signal.

The enclosure is a Powder Coated Black Prismatic Cosmos with white fluted knobs. The jacks are all Lumberg and the vinyl labels on the enclosure are clear coated.

SPECS

• True bypass JFET clean boost
• Two controls : Input (bass and gain attenuator), Output (master volume)
• 9V DC center negative, 5mA

The Fumble has two knobs, true bypass switching, and creates a particularly enhanced clean tone.

OUTPUT is your master volume. Turn it up for more volume.

INPUT is the one that surprises people. It is not a standard gain knob. It attenuates bass and input gain at the front of the circuit simultaneously. Fully right has no cut — consider it a bypass of the control. As you turn the knob to the left, bass and gain are gradually attenuated. Roll it down for a thinner, tighter response. Roll it up for a fuller, louder one. There is almost nothing else on the market that boosts in this way.
