1590B Drill Guide

There is a small error on the PCB where the Volume and Fuzz pots are slightly out of alignment on

the horizontal axis (they are a little less than 1mm off from one another). The drilling template above

corrects that and has them perfectly in line.

You can install the PCB directly in the re-aligned drill holes. Bend the pins of the Vol pot inward slight-

ly if you wish, or just over-drill the hole for the Fuzz pot by a stop.

This error will be fixed on the next batch of boards.
