The Coppersound/JHS Boost-a-Drive Fuzz is a DIY pedal kit, not a finished pedal: a build-it-yourself release made in collaboration between JHS and CopperSound. One circuit covers three gain stages of attack, selected by a three-position mode switch: Boost, Drive and Fuzz1.
What it does
Delicious Audio describes the pedal as taking "the classic two-transistor LPB-1 architecture and evolves it into a dynamic, multi-mode saturation engine." In practice that means one box that moves through cascading gain behaviors: the feel of high-headroom boosters, amp-like dynamic overdrive, and aggressive Fuzz Face-style square-wave fuzz1. If you are mapping it against other effect types, it touches boost, overdrive and fuzz territory in a single enclosure.
Controls
| Control | What it does |
|---|---|
| Mode selector | Three modes: Boost, Drive, Fuzz1 |
| Gain | Dedicated gain pot1 |
| Master Volume | Dedicated master volume pot1 |
| Tone | Passive low-pass tone filter, comparable to a RAT-style EQ knob1 |
| Internal trim pots | Internal biasing trim pots1 |
The internal biasing trim pots are the kind of control a finished pedal usually hides, which makes sense for a kit: they let the builder set the transistor bias as part of the build1.
Where the circuit comes from
The design is credited to Josh Scott. Delicious Audio reports the pedal was "Born from Josh Scott's Short Circuit series and produced in collaboration with CopperSound"1. The underlying topology is a dual high-gain transistor design, an evolution of the two-transistor LPB-1 circuit1.
What reviewers said
Delicious Audio reports that independent builder communities and gear roundups praise the pedal's broad, highly responsive gain sweep, noting that every millimeter of the sweep yields distinct, usable textures bridging transparent line-pushing and jagged, touch-sensitive breakup1.
Questions
Is the Coppersound/JHS Boost-a-Drive Fuzz a kit or a finished pedal?
It is a DIY pedal kit, released in collaboration between JHS and CopperSound. The buyer solders and assembles the pedal themselves rather than receiving a finished unit. It grew out of Josh Scott's Short Circuit series and was produced with CopperSound.
What are the three modes on the Boost-a-Drive Fuzz?
A three-position mode selector offers Boost, Drive and Fuzz. Delicious Audio describes the circuit as merging cascading gain behaviors that channel the feel of high-headroom boosters, amp-like dynamic overdrive, and aggressive Fuzz Face-style square-wave fuzz.
What are the internal trim pots on the Boost-a-Drive for?
The kit includes internal biasing trim pots, used for biasing the circuit's transistors. Alongside them the pedal has dedicated Gain and Master Volume pots on the outside, plus a passive low-pass tone filter comparable to a RAT-style EQ knob.
Who designed the Boost-a-Drive Fuzz?
The design is credited to Josh Scott of JHS. Delicious Audio reports that the pedal was born from his Short Circuit series and produced in collaboration with CopperSound.
