About this drill template
Drill template for the Fuzz Dog Little Boy Blues Drive, 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: “Of course the world always needs another Tube Screamer based drive, right?”
The Blue Boy Deluxe, another turn on the Tube Screamer with far more control than the original. Six knobs on a 50 x 36mm board.
Build notes
Six knobs is the practical limit for a single-row layout, used for complex circuits where the extra parameters genuinely change the sound rather than just trimming it.
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 36mm, 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.
