{"type":"firestarter.listing","listing":{"id":"lst_8l4_aEqY","product_name":"FUMBLE","category":"BOOST","description":"The Fumble exists because we made the biggest mistake in JHS history.\nIn May of 2025, we released the NOTADÜMBLË — our second solderless DIY kit pedal, containing two of the most coveted sounds from the Dumble universe. 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. John Mayer owns one of these obscure units and lent it to us. I replicated it, named it Box It Later, and that replica has traveled the world on John's pedalboards consistently since 2021.  I thought I put that circuit in the NOTADÜMBLË as the clean side.\nI didn't.\nA week after launch, while planning a Short Circuit episode video about the NOTADÜMBLË, I discovered I had used the wrong circuit. The clean side of the NOTADÜMBLË wasn’t the  “A Box Later”– it was something else entirely. Something I had also reverse engineered back in 2019 also for John, and then completely forgotten about. A separate Dumble preamp box that lived in a different archive location in our R&D storage. I had confused the two similar circuits and made a horrible mistake.\nI made a video. I told everyone. We sold through the remaining  inventory, discontinued the NOTADÜMBLË V1 after our batch of 15,000 sold out, and refunded anyone who asked to return their unit.\nEnter the Fumble.\nWHAT THE FUMBLE ACTUALLY IS\nThe Fumble is a faithful production version of the other circuit I cloned for John: the Dumble BBC-1. Once the NOTADÜMBLË V1 was discontinued, customers started telling us how much they loved that circuit and how they wished it was sold separately. The Fumble is that exact circuit, now in its own compact enclosure with its own self-deprecating name, an $89 price point, and no kit to build.\nHere is where the story gets s","images":["https://cdn.shopify.com/s/files/1/0610/7122/9028/files/JHS-Pedals-Fumble-Front.png?v=1780345329","https://cdn.shopify.com/s/files/1/0610/7122/9028/files/JHS-Pedals-Fumble-QL.png?v=1780345330","https://cdn.shopify.com/s/files/1/0610/7122/9028/files/JHS-Pedals-Fumble-QR.png?v=1780345330","https://cdn.shopify.com/s/files/1/0610/7122/9028/files/Fumble-JHS-Pedals-10.jpg?v=1780345345","https://cdn.shopify.com/s/files/1/0610/7122/9028/files/Fumble-JHS-Pedals-14.jpg?v=1780345365","https://cdn.shopify.com/s/files/1/0610/7122/9028/files/Fumble-JHS-Pedals-16.jpg?v=1780345386","https://cdn.shopify.com/s/files/1/0610/7122/9028/files/Fumble-JHS-Pedals-17.jpg?v=1780345393","https://cdn.shopify.com/s/files/1/0610/7122/9028/files/Fumble-JHS-Pedals-20_4a6a6e02-741d-4c53-b0c8-18c405fd57a2.jpg?v=1780345404","https://cdn.shopify.com/s/files/1/0610/7122/9028/files/Fumble-JHS-Pedals-22.jpg?v=1780345408","https://cdn.shopify.com/s/files/1/0610/7122/9028/files/Fumble-JHS-Pedals-15.jpg?v=1780345417"],"price":89,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:09.074Z"},"share_url":"https://firestarter.network/l/lst_8l4_aEqY","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
