Fumble is a special pedal created by JHS. They released the NOTADÜMBLË, the second DIY pedal kit without soldering, which contains sounds related to Dumble. The overdrive side offers a boutique sound, known from artists like Larry Carlton, Eric Johnson, and Robben Ford.

The clean side of the NOTADÜMBLË, however, was intended to be a reproduction of the "A Box Later" device, but the final version included a different circuit. The discovery of the error occurred while designing materials for the product presentation, and JHS decided to discontinue the production of the NOTADÜMBLË V1, informing customers and refunding their money.
