The V1 accidentally had the wrong boost circuit. The V2 fixes that and gives several more new features. We added a second footswitch, an effects loop, an order toggle, and moved the Presence trim pot to the face of the pedal.

The first was the A Box Later, a device Howard Dumble built sometime in the 1980s as a buffer preamp boost with a built-in effects loop. John has used it in several situations over the years. We cloned it, named it the Box It Later, and that pedal has lived on versions of Mayer's pedalboards since 2021.\u003c\/span\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThe second unit was the Dumble BBC-1, a far more obscure preamp boost. We cloned that one too and made John a private copy called the Basic Boost. At the time Josh assumed he was simply cloning a JFET booster that Howard threw together. He didn't know that years later he would discover that Dumble's BBC-1 was itself a near-part-for-part clone of a Barcus Berry acoustic preamp from the 1970s. The legendary Dumble FET sound — the one inside $200,000 to $400,000 amplifiers — is a clone of a piezo preamp. That rabbit trail belongs to the Fumble, not this pedal. Check it out here. \u003c\/span\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThe NOTADÜMBLË V1 was always supposed to use the Box It Later circuit as its clean channel. The one John actually uses. Two weeks after launch, while prepping a Short Circuit episode about modding the kit, we discovered we had used the BBC-1 instead. The two units look similar. They sound similar. They were both built by Howard, both clean boosts, both reverse engineered for John in 2019. Cliff Smith, our head of R\u0026amp;D at the time, did most of that reverse engineering. His notebooks were the documentation. Cliff passed away a few months after we shipped John's replicas, and when the NOTADÜMBLË kit was greenlit years later, the wrong schematic was the one that got pulled. It slipped through the cracks. \u003c\/span\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eI made a video called \"The Biggest Mistake I've Ever Made.\" I told everyone. We sold through the remaining V1 inventory, discontinued the kit after our batch of 15,000 sold out, and refunded anyone who asked. Then we released the BBC-1 as its own pedal — the Fumble — so the circuit V1 owners loved didn't disappear. \u003c\/span\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThis is the V2.
