Engineered as an ambitious hybrid utility box, the JHS/Coppersound Boost-a-Drive Fuzz is a DIY kit released in collaboration with the folks at Coppersound.
Born from Josh Scott’s Short Circuit series and produced in collaboration with CopperSound, the Boost-a-Drive Fuzz is a multi-stage hybrid circuit that takes the classic two-transistor LPB-1 architecture and evolves it into a dynamic, multi-mode saturation engine. Rather than simply copying a single vintage topology, it merges cascading gain behaviors that channel the feel of high-headroom boosters, amp-like dynamic overdrive, and aggressive, Fuzz Face-style square-wave fuzz into a single interactive platform.
Key Specs:
- Dual high-gain transistor topology,
- 3-mode Mode selector: Boost, Drive, Fuzz
- Passive low-pass tone filter, (comparable to a RAT-style EQ knob)
- Dedicated Gain and Master Volume pots
- Internal biasing trim pots
The Consensus: Independent builder communities and gear roundups praise its broad, highly responsive sweep. Reviewers note that because you are actively adjusting the circuit’s operating point with the gain control, every millimeter of the sweep yields distinct, usable textures—bridging the gap between transparent line-pushing and jagged, touch-sensitive breakup.
