Insert the plug onto the 7 pin header
of the pickup as shown above.
Note the orientation arrow.
Using the Pot Section as:
2) The Pickup Tone control or as a Master Tone control for the instrument.
Refer to Diagrams #5 and #6
The pot section (25KA) can be used either as a Tone control
for the pickup or it can be used as a Master Tone control for the guitar.
Diagrams #5 and #6 show how to connect either option.
Use the dual-line header, push the cables on and install the shunts
as needed onto headers H1 thru H6.
Use Diagram #5 if you have a single 57-TW installed in your instrument,
or have two or more pickups in your instrument and want to use the pot as the
Tone control for the 57-TW Pickup only.
Installing the shunt on position H4 connects a tone capacitor on the PC Board
to the wiper of the 25K Pot and creates a passive Tone control. The output of
pickup can be either position H1 or H2.
Diagram #6 uses the 25K Tone control independently of the pickup output.
By taking the output of the pickup from Position H5, the control is now
available to use as a Tone Control independent of the pickup output.
Position H3 is the input to the Tone Control, with H1 or H2 being the output of
the control, if necessary.
Position H5, the output of the pickup, would typically go to a selection switch
or output jack.
