Fumble Clean Boost
The Fumble might be the only pedal in history born from a quality-control mistake — and named after it. When JHS shipped the first run of its NOTADÜMBLË DIY kit in 2025, the boost side accidentally contained the wrong circuit: instead of the intended booster, builders got a JFET recreation of the Dumble BBC-1, the ultra-rare clean boost/preamp that Alexander Dumble built for a handful of players, most famously John Mayer. Rather than bury the error, Josh Scott did the most JHS thing possible: he owned the fumble, put the accidental circuit in its own enclosure, and sold it for $89. The Fumble is beautifully simple — just Input and Output knobs, mirroring the BBC-1's gain-staging approach. Set the input level to push the JFET stage into subtle, amp-like thickening, then balance your overall level with the output. Used gently, it is a transparent-ish boost with a pleasing analog sheen; pushed harder, it adds the harmonic glow and midrange focus that made Dumble gear mythical. Because it is a preamp at heart, it shines at the front of a chain, warming everything downstream — an always-on tone conditioner in the tradition of the Klon-as-buffer school, but with D-style pedigree. It is also proof that the best pedal stories are true ones: an accidental recreation of one of the rarest boost circuits ever made, now available for less than a night out. Every fumble should end this well.
