About this drill template
Drill template for the Fuzz Dog Mastodon Bass Fuzz, 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 5-knob layout, with 1 toggle. Print at 1:1 scale, tape to the enclosure face, centre-punch, and drill. PCB and parts not included.
Fuzz Dog description: “Absolutely massive fuzz designed for bass but just as brutal on guitar - honest!”
The Mastotron, a big fuzz built for bass that is just as brutal on guitar. Its SUBS switch sets how much low end the pedal pushes out across three positions, so it is part of the standard build.
Build notes
Five-knob designs typically reserve the extra pot for a tone shaping control: a presence, a mid scoop, or a parametric centre frequency.
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 easy.
Drill measurements
Hole centres for the 1590B 5-Knob 1-Toggle (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.
