The remaining components and wires can be connected to the upper portion of their respective
terminals. Unless otherwise noted, “mount” means to mount the component, solder the component in
place and trim the leads.
mount the positive end to terminal 5.

Mount footswitch in ½” hole. Large nylon washer
goes under mounting nut on outside of box. Lock
washer mounts on inside of box between the box
surface and the other nut. Make sure that the
footswitch solder lugs are oriented left to right, not
up and down as illustrated here.

Please refer to DRAWING 3.
Mount the 5K potentiometer in the upper left hole using hardware provided. Mount the 250K
potentiometer in the upper right hole using the hardware provided. Solder lugs for both pots should
be pointed toward the bottom side of the enclosure. (
Remove the small mounting tab on each pot
by bending it back with pliers and clipping it off with cutters).

Correct Orientation
This component
is delicate, be
careful not to
burn it or break
off the leads by
bending them
repeatedly.
Caution: MOSFETs can easily be damaged by static electricity. Handle with care.
