SECTION 1 – Mount LED, ¼” Jacks and Terminal Strip Components
Please refer to DRAWING 1 and DRAWING 2.
Orient the box with the ½” hole nearest you.
2) Mount input jack in the 3/8" hole on left side of box with hardware provided.
3) Mount output jack in the 3/8" hole on right side of box with hardware provided.
4) Mount the terminal strip to the 1/8" hole as shown in drawing 2.

Unless noted otherwise, connect and solder all of the following to their respective connection points
as stated. (Make sure none of the component leads are so close together that they could lead to an
unintended connection).
Be careful not to overheat the solid state devices (diodes and transistor)
when soldering.
5) Strip and tin a 1 ½” piece of wire and connect terminal #1 to #3.
Washer goes under nut on outside of box. Make sure center “ground” lug of input
jack is facing up. Correct positioning of jack will make soldering connections much
easier. When positioned correctly, tighten nut.
Washer goes under nut on outside of box. Make sure the “tip” lug is on top
(towards the enclosure opening) before tightening nut.
We will refer to terminal numbers from “1” to “5” as illustrated.
You might want to connect to the lower terminal holes to leave room for other
components.

1) Mount the LED in the ¼” hole below the distortion pot’s
mounting hole. The lock washer goes over the threaded
portion prior to insertion through the top of the enclosure.
Align the LED leads so that the anode (long lead) is closer to
where the terminal strip will be as shown in Drawing 2.
The Anode (+) side of the LED is
indicated by a slightly longer lead
and/or a positive sign.

The orientation of the jacks is shown in the drawings is for ease of soldering and clarity in
the diagram. The jacks may need to be rotated so the tip does not touch the chassis when a
cable is plugged in.
