SECTION 1 – Mount Large Components

Stripping wire, tinning wire and soldering.

Throughout these instructions you will be told to strip 

and tin a length of wire numerous times.  Unless noted otherwise, cut the wire to the length stated in 
the instructions.  Then strip ¼” of insulation off each end.  Twist each end of the stranded wire, and 
apply a small amount of solder to each end (i.e. tin the wire ends).

Please refer to DRAWING 1 and DRAWING 2.

Orient the enclosure with the two 5/16" holes on top.

Using the seven screws, nuts and lock washers provided, fasten the five terminal strips to match 
DRAWING 2.

Fasten the two 5 lug 
terminal strips and the 3 
lug terminal strips first.  
Then fasten the two 8 
lug terminal strips.

Mount the 1KL pot in the 5/16" hole on the left and the 500KA pot in the 
remaining 5/16" hole on the right.

Bend back and remove the alignment tab on the top of each potentiometer 
using a pair of pliers before mounting the pots so that they can mount flush 
against the enclosure surface.

Mount the DC power jack in the 15/32" hole on the left 
side of the enclosure.  Orient its solder lugs so that 
the center-pin lug is facing the bottom side of the 
enclosure.

POSITIVE LUG

Mount the input jack in the 3/8" hole on the left side of the enclosure with the hardware provided.  
The washer goes under the nut on the outside of the enclosure.  Make sure the center solder lug of 
the input jack is facing up.  Correct positioning of the jack makes soldering the connections easier.

Mount the output jack in the 3/8" hole on the right side of the enclosure.  Make sure the two solder 
lugs are in their most upright position before tightening the nut.

Mount the footswitch in the 15/32" hole in the center of the enclosure.  The nylon washer goes 
under the mounting nut on the outside of the enclosure.  Then the lock washer mounts on the inside 
between the enclosure surface and the other nut.  Make sure that the footswitch is oriented to match 
DRAWING 2.

SECTION 2 – Wire Large Components
Please refer to DRAWING 3.

Please note that each terminal has been numbered as 
illustrated here and will be referred to as a “

terminal #_

”  when 

connecting different components and wires throughout the 
assembly instructions.

This will prevent the stranded wire from fraying and will make the 
final soldering much easier.
