After JHS discovered that the clean side of the NOTADÜMBLË V1 accidentally contained the wrong circuit, players started asking for that mistakenly included sound as a pedal of its own. The circuit traces back to a Dumble BBC-1 unit that JHS reverse engineered for John Mayer, connecting it to the FET-style clean boost sounds often associated with players like Larry Carlton, Eric Johnson and Robben Ford.\u003c\/p\u003e\u003cp\u003eIt's a clone of a clone with real pedalboard utility. JHS later discovered that the original BBC-1 itself appears to draw heavily from a 1970s Barcus Berry acoustic preamp design, and that unusual lineage gives the Fumble its personality. It isn't a high-gain drive, a traditional transparent overdrive or a typical clean boost — it behaves like a JFET preamp that adds size, clarity and articulation before your overdrives, into a clean amp or at the end of the chain.\u003c\/p\u003e\u003cp\u003eThe two-knob layout is simple, but the Input control doesn't work like the gain knob on most boosts. Output is the master volume, while Input simultaneously attenuates bass and front-end gain entering the circuit. Fully clockwise, the signal stays full, open and louder; rolling it back gradually tightens the low end while thinning and focusing the response. That makes the Fumble equally at home as an always-on boost, a JFET preamp into pedals like a Timmy, King of Tone, Klon or Morning Glory, a front-end push into a dirty amp, or a solo lift near the end of the signal chain.\u003c\/p\u003e\u003cp\u003eInto a clean amp, the Fumble adds presence and clarity without pushing things fully into overdrive. Into a broken-up tweed, a Plexi-style amp or a gain pedal, it makes the response feel larger, tighter and more defined — especially with the Input rolled back for a more focused attack. True bypass switching, 9V DC center-negative power and a compact enclosure assembled in Kansas City round out a pedal built for players shaping touch sensitivity and note definition rather than chasing heavier saturation.\u003c\/p\u003e\u003cp\u003e\n\u003c\/p\u003e\u003ch4 style=\"font-size:1.5em;\"\u003eSPECIFICATIONS\u003c\/h4\u003e\u003cp\u003e\n\u003c\/p\u003e\u003cp\u003e• Product Type: Clean boost pedal\u003c\/p\u003e\u003cp\u003e• Model: Fumble\u003c\/p\u003e\u003cp\u003e• Effect Type: JFET clean boost\u003c\/p\u003e\u003cp\u003e• Bypass: True bypass\u003c\/p\u003e\u003cp\u003e• Input Control: Bass and gain attenuator\u003c\/p\u003e\u003cp\u003e• Output Control: Master volume\u003c\/p\u003e\u003cp\u003e• Power Requirements: 9V DC center negative\u003c\/p\u003e\u003cp\u003e• Current Draw: 5mA\u003c\/p\u003e\u003cp\u003e• Length: 3.93\"\u003c\/p\u003e\u003cp\u003e• Width: 1.96\"\u003c\/p\u003e\u003cp\u003e• Height: 1.21\"\u003c\/p\u003e\u003cp\u003e• Country of Origin: United States\u003c\/p\u003e\u003cp\u003e\n\u003c\/p\u003e\u003cp\u003eModel# FB\u003c\/p\u003e","brand":"JHS Pedals","offers":[{"title":"Default Title","offer_id":62719505301585,"sku":"108049","price":89.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/8936\/5585\/files\/img_5b5630f1a1e5.png?v=1790186385","url":"https:\/\/www.musiciansbuy.com\/products\/jhs-the-fumble-jfet-clean-boost-pedal","provider":"MusiciansBuy.com","version":"1.0","type":"link"}
