About this drill template
Drill template for the PedalPCB 6-Band EQ (Potentiometer Version), sized for a Hammond 125B enclosure (64 × 119 × 35 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.
EQ pedals — graphic or parametric — let you reshape the signal between gain stages. Graphic EQs use a row of sliders (or pots) for fixed bands; parametric EQs give you frequency and Q on top of gain. The drill template handles whichever this is.
Build notes
Six-knob layouts are about as much as a single-row enclosure comfortably fits — modulation depth, multi-band EQ, multi-stage compression all live here.
The Hammond 125B is one of the most common DIY pedal enclosures — a touch larger than a 1590B, slightly smaller than a 1590BB, with room for almost any single-effect PCB plus 9V supply.
Vendor specs: Designed for a 125B enclosure with top-mounted jacks
