Base pedal: JHS Fumble Boost / Dumble BBC-1
Compared to the Dumble BBC-1 and the JHS NOTADüMBLë, this is a clean boost rooted in the famously expensive, near-mythical Dumble amplifier preamp circuit. Dumbles are among the most coveted and inaccessible amplifiers ever made, so capturing their clean-channel clarity and touch-sensitivity in a stompbox — at DIY cost — is an appealing proposition for any player chasing that elusive, glassy headroom.
