About this drill template
Drill template for the PedalPCB CDXL Classic Envelope Filter, 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 2-knob layout. Print at 1:1 scale, tape to the enclosure face, centre-punch, and drill — PCB and parts not included.

Build notes
Two-knob builds are usually the cleanest internally — minimal pot wiring, easy to keep the signal path short.
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
