The overdrive side was correct: a boutique style overdrive built around the lead tone people associate with Larry Carlton, Eric Johnson, and Robben Ford. The clean side, however, was supposed to be a reverse engineered copy of the \"A Box Later,\" a buffered effects loop device that Howard Dumble built sometime in the 1980s outside of his amplifier designs.\u003c\/p\u003e\n\u003cp data-start=\"592\" data-end=\"919\"\u003eA week after launch, while planning a Short Circuit episode video about the NOTADÜMBLË, we discovered the wrong circuit had been used. The clean side of the NOTADÜMBLË wasn’t the “A Box Later”– it was a separate Dumble preamp box that had been reverse engineered years earlier and mistakenly confused with the intended circuit.\u003c\/p\u003e\n\u003cp data-start=\"921\" data-end=\"1060\"\u003eThe remaining inventory was sold, the NOTADÜMBLË V1 was discontinued after 15,000 units, and customers who requested returns were refunded.\u003c\/p\u003e\n\u003cp data-start=\"1062\" data-end=\"1093\"\u003e\u003cstrong data-start=\"1062\" data-end=\"1093\"\u003eWhat the Fumble Actually Is\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"1095\" data-end=\"1293\"\u003eThe Fumble is a faithful production version of the Dumble BBC-1 circuit. Once the NOTADÜMBLË V1 was discontinued, customers began asking for that clean circuit to be available as a standalone pedal.\u003c\/p\u003e\n\u003cp data-start=\"1295\" data-end=\"1584\"\u003eFurther research revealed that the BBC-1 was based on a JFET preamp derived from a 1970s Barcus Berry acoustic preamp. Howard Dumble adapted the design into a standalone enclosure for a small number of players and later incorporated the same JFET stage into his amplifiers as the FET mode.\u003c\/p\u003e\n\u003cp data-start=\"1586\" data-end=\"1699\"\u003eThe Fumble recreates that circuit in a compact enclosure with a simple control layout and affordable price point.\u003c\/p\u003e\n\u003cp data-start=\"1701\" data-end=\"1717\"\u003e\u003cstrong data-start=\"1701\" data-end=\"1717\"\u003eWhat It Does\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"1719\" data-end=\"1815\"\u003eThe Fumble has two knobs, true bypass switching, and creates a particularly enhanced clean tone.\u003c\/p\u003e\n\u003cp data-start=\"1817\" data-end=\"1853\"\u003eOUTPUT is the master volume control.\u003c\/p\u003e\n\u003cp data-start=\"1855\" data-end=\"2125\"\u003eINPUT is not a standard gain control. Instead, it simultaneously attenuates bass and input gain at the front of the circuit. Fully clockwise applies no cut. As the control is turned counterclockwise, bass and gain are gradually reduced for a tighter and leaner response.\u003c\/p\u003e\n\u003cp data-start=\"2127\" data-end=\"2155\"\u003e\u003cstrong data-start=\"2127\" data-end=\"2155\"\u003eUse the Fumble Four Ways\u003c\/strong\u003e\u003c\/p\u003e\n\u003col data-start=\"2157\" data-end=\"2382\"\u003e\n\u003cli data-section-id=\"roh8mx\" data-start=\"2157\" data-end=\"2225\"\u003eAs a permanent buffer and clean boost at the front of your board.\u003c\/li\u003e\n\u003cli data-section-id=\"1s6397l\" data-start=\"2227\" data-end=\"2272\"\u003eTo push the front end of overdrive pedals.\u003c\/li\u003e\n\u003cli data-section-id=\"1kcs79h\" data-start=\"2274\" data-end=\"2330\"\u003eTo drive the front end of an already dirty amplifier.\u003c\/li\u003e\n\u003cli data-section-id=\"rlm9nc\" data-start=\"2332\" data-end=\"2382\"\u003eAs a solo boost at the end of the signal chain.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp data-start=\"2384\" data-end=\"2403\"\u003e\u003cstrong data-start=\"2384\" data-end=\"2403\"\u003eWho This Is For\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"2405\" data-end=\"2507\"\u003eIf you bought the NOTADÜMBLË V1 and enjoyed the clean section, this is the circuit that was inside it.\u003c\/p\u003e\n\u003cp data-start=\"2509\" data-end=\"2618\"\u003eIf you missed it, the Fumble delivers a simple JFET clean boost with a unique control set and tonal response.\u003c\/p\u003e\n\u003cp data-start=\"2620\" data-end=\"2642\"\u003e\u003cstrong data-start=\"2620\" data-end=\"2642\"\u003eWho This Isn't For\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"2644\" data-end=\"2889\"\u003eThis is not an overdrive or high-gain pedal.
