From the post
And improvement over the original English Channel project, the Run Off Groove Britannia is an adaption of the classic Vox AC-30 amp into stompbox form. Couldn't squeeze this one into a 1590B with onboard pots, but it's laid out for a 125B enclosure. Pots are right angle PCB mount type, mounted from the solder-side of the board. Check out the ROG project page for a full description, schematic, and sound clips of this circuit.
You can find a 125B drilling template for this here.
