About this drill template
Drill template for the Fuzz Dog Acti-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 4-knob layout. Print at 1:1 scale, tape to the enclosure face, centre-punch, and drill. PCB and parts not included.
Fuzz Dog description: “A nice pair of boosts/tone shapers, both of which can be made using the same PCB (though only one at a time - come on!).”
One board that builds either of two related boost and tone shaper circuits, the AC and the RC. Both are clean boosts with active bass and treble controls, so they work as an always-on tone shaper as much as a level lift.
The PCB supports both versions, but you pick one at build time: the parts differ between them.
Build notes
Four-knob layouts are dense but manageable: the pots are spaced wide enough to grab individually, with the footswitch centred below.
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 4-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.
