About this drill template
Drill template for the PedalPCB NuDrive, sized for a Hammond 125B enclosure (63.7 × 119.4 × 35.8 mm). The pre-positioned holes match the PCB's pot footprint exactly, with the footswitch centred below the 3-knob layout. Print at 1:1 scale, tape to the enclosure face, centre-punch, and drill. PCB and parts not included.
Overdrives and boosts overlap heavily, the line between 'breakup' and 'level' is mostly about how the clipping stage behaves at low signal levels. This circuit's controls are positioned in the template the way a player would actually use them on the floor, not the way they look best in a photo.
Build notes
Three-knob layouts give you the full gain / EQ / volume triplet without crowding the enclosure. There's room inside for the PCB, jacks, and a 9V supply.
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: Utilizes the Korg NuTube 6P1. Includes 6P1 carrier PCB. Designed for a 125B enclosure with top-mounted jacks
