About this drill template
Drill template for the Fuzz Dog Karryn, 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: “Now discontinued Japanese boutique take on emulating a cranked 70s era Marshall.”
A now-discontinued Japanese boutique overdrive built around the sound of a cranked 1970s Marshall. Simple control set, with the character coming from the voicing rather than from a lot of knobs.
Build notes
Three-knob layouts give you the full gain / EQ / volume triplet without crowding the enclosure. There's room inside for the PCB, jacks, and a 9V supply.
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 40mm, build difficulty medium.
Drill measurements
Hole centres for the 1590B 3-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.

Never drilled one before? How to drill a pedal enclosure walks you through the entire process, from punching the centres to the final step drill size.
Jig A covers 1590B 3-Knob (Type 1)
Drop it over the enclosure, punch a mark through the holes this build uses, then lift it off and drill. It wraps onto the sides too, so the jacks and DC socket are covered.
