About this drill template

Drill template for the Fuzz Dog Secret Screamer, 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 3-knob layout. Print at 1:1 scale, tape to the enclosure face, centre-punch, and drill. PCB and parts not included.

Fuzz Dog description: “One of those pedals that came and went in a flash, got snapped up and is now likely a decent chunk of a lot of people's retirement funds...”

The TSV808. The stock build is three knobs, with Bass and Sat as internal trimmers and the clipping selection on an internal DIP switch. Fitting pots and toggles instead takes it to five knobs and two switches.

Build notes

Three-knob layouts are the most common pedal format (gain, tone, level) with the pots centred above the footswitch.

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 53mm, build difficulty medium.
