About this layout
The 125B 1-Knob (Type 1) template positions 6 holes (63.6 × 119.3 × 35.8 mm): Pot, LED, Footswitch on the enclosure face; DC Jack, 2 × Jack on the top side. Every circuit listed below shares these hole positions, so one printed template covers any of them. Print the PDF at 1:1 scale, tape it to the enclosure, centre-punch, and drill.

Jig A covers 125B 1-Knob (Type 1)
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.
