About this drill template
Drill template for the Fuzz Dog Watchman Optical Compressor, 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 6-knob layout. Print at 1:1 scale, tape to the enclosure face, centre-punch, and drill. PCB and parts not included.
Fuzz Dog description: “Keep a watchful eye on your signal with this optical compressor.”
The Warden, an optical compressor. Its only jumper decision is which charge pump you fit, so all six holes are knobs.
Build notes
Six-knob layouts are about as much as a single-row enclosure comfortably fits: modulation depth, multi-band EQ, multi-stage compression all live here.
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 50 x 50mm, build difficulty medium.
Drill measurements
Hole centres for the 1590B 6-Knob (Type 1) layout. X runs left to right from the centre of the face being drilled. On the enclosure face, Y is measured from the centre, positive towards the top. 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.
