About this drill template
Drill template for the Aion FX Aphelion Vintage Distortion, sized for a Hammond 125B enclosure (63.6 × 119.3 × 35.8 mm). The pre-positioned holes match the PCB's pot footprint exactly, with the footswitch centred below the 2-knob layout, with 2 toggles. Print at 1:1 scale, tape to the enclosure face, centre-punch, and drill. PCB and parts not included.
Aion FX description: “Based on the MXR® Distortion+ and DOD 250, one of the first drive circuits to use an op-amp.”

Jig A covers 125B 2-Knob 2-Toggle w/ Battery
Drop it over the enclosure, punch a mark through the holes this build uses, then lift it off and drill. It wraps onto the sides too, so the jacks and DC socket are covered.
