STEP 2: Installing the Stereo Jack
Disconnect the wires and remove the existing output jack from the guitar.
•
Install the new stereo jack. The stereo jack is the same physical size as a
•
standard stereo jack and should fit in most guitars without requiring any
physical modifications.
STEP 3A: Wiring without a Pre-Amplifier
If you are installing the Acousti-Phonic Intelligent Pre-amp, skip to STEP
3B, page 12. If you are not installing an Acousti-Phonic Intelligent Pre-amp, the
guitar may now be wired using the passive volume potentiometer (pot).
Install the volume pot.
•
The volume pot is most conveniently installed in place of an existing pot. For
Tele style instruments this will likely be the Tone control. For Strat
®
ments this will likely be the second Tone control.
The replaced control may be sacrificed, or it may be moved to share a knob with
another existing control by fitting a push-pull double pot or similar arrangement.
Alternatively, if there is room, a new hole may be drilled and an entirely new pot
may be added.
Regardless of the arrangement chosen, it is important that the volume pot used
for the GHOST pickups is a 5 Mega Ohm type. Lower value types are not suitable
due to the very high impedance of the GHOST pickups.
The diagram below (Diagram 4) shows the schematic for an installation with a
passive volume control.
