About this drill template
Drill template for the Fuzz Dog May 83 Treble Boost, sized for a Hammond 1590B enclosure (59.3 × 111.2 × 27 mm). The pre-positioned holes match the PCB's pot footprint exactly, with the footswitch centred below the 1-knob layout. Print at 1:1 scale, tape to the enclosure face, centre-punch, and drill. PCB and parts not included.
Fuzz Dog description: “Another treble boost used by Mr May. This one can be seen in photos of his pedal board from 1981.”
The TB83, another of the treble boosts Brian May has used, this one visible in photographs of his pedal board from 1981. Single control and an easy build.
Build notes
The Hammond 1590B is the standard small DIY pedal enclosure: compact enough for a crowded board, large enough for most single-effect PCBs and a 9V battery.
Vendor specs: PCB 25 x 22mm, build difficulty easy.
Drill measurements

For holes on a side, Y is the distance down the wall, measured from the face edge. Export the PDF for a 1:1 printable version with a scale check.
