About this drill template
Drill template for the Aion FX Emerald Resonant Phaser, 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 4-knob layout. Print at 1:1 scale, tape to the enclosure face, centre-punch, and drill. PCB and parts not included.
Aion FX description: “A four-stage JFET-based phaser similar to the Phase 90, but with with a frequency-dependent feedback control that accentuates the phase effect.”
Drill measurements
Hole centres for the 125B 4-Knob 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.

Jig A covers 125B 4-Knob
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.
