About this drill template
Drill template for the PedalPCB XB-MB Preamp, 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 5-knob layout. Print at 1:1 scale, tape to the enclosure face, centre-punch, and drill — PCB and parts not included.
PedalPCB description: “Compare to Xotic BB Preamp Mid Boost”
Build notes
Five-knob designs typically reserve the extra pot for a tone shaping control — a presence, a mid scoop, or a parametric centre frequency.
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
