SHUNT ON H3
2) A Master Tone control for the instrument or, the Pickup Tone control
Refer to Diagrams #5 and #6
TO VOLUME CONTROL
The pot section (25KA) can be used either as a Tone control
SELECTION SWITCH OR...
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 10-pin header and push the cables on and
install the shunts as needed onto the labeled headers H1 thru H5.
Use Diagram #5 if you have a single 40-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 40-TW Pickup only.
Installing the shunt on position H3 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 the is at position H1.
OUTPUT OF TONE CONTROL
Diagram #6 uses the 25K Tone control independently of the pickup output.
H1 (ONLY IF NEEDED)
By taking the output of the pickup from Position H4, the control is now
INPUT TO TONE CONTROL
available to use as a Master Tone with H1 and H2 being the input and/or output
H2
of the Tone control. H1 and H2 positions are interchangeable.
Position H4, the output of the pickup, would typically go to a selection switch
PICKUP OUTPUT H4
or a pan-pot.
