Installation instructions

PICKUP INSTALLATION
Installation for Biscuit style instruments:
The pickup is held against the center of the cone with the wood screw that normally
holds the biscuit to the cone.
1. Remove the original screw from the biscuit and swap it with the longer wood
screw that is supplied with the kit.
2. Notice that the heat-shrink tubing on the end of the pickup is bent to one side.
Do not attempt to unbend it! If you do so you may damage the pickup. Position
the pickup so the bend in the heat shrink tubing faces away from the cone.
3. Place the shoulder washer into the pickup. Then place the the screw into the
shoulder washer and fasten the entire assembly to the cone/biscuit. Tighten
the screw until snug, and then another 1/8 turn tighter.
4. Re-assemble the instrument.
Installation for Spider style instruments:
This installation is a little trickier than the biscuit installation. For the pickup to oper-
ate properly it is critical that the spider and cone are pre-loaded with the correct
pressure.
1. With the instrument tuned to pitch, calibrate the spider/cone pressure by loos-
ening the screw that holds the cone to the spider until the screw head no longer
touches the spider frame. Tighten the screw until the head just touches the spi-
der, and then tighten one full turn more. The spider/cone is now pre-loaded for
optimum bass response without buzzes or rattles.
2. Remove the strings and the cone/spider assembly.
3. If the end of the screw is long enough to accept the pickup and locknut, go on
to the next step. If it is not long enough you will need to replace it with a longer
screw and go back to step #1. We include replacements for both SAE 4-40 and
3mm screws, plus matching locknuts in the hardware kit. Choose the screw
that matches the threaded slug in the center of the cone assembly.
4. Notice that the heat-shrink tubing on the end of the pickup is bent to one side.
Do not attempt to unbend it! If you do so you may damage the pickup. Position
the pickup so the bend in the heat shrink tubing faces away from the cone.
5. Place the pickup, then the shoulder washer on the screw and start to thread the
lock nut. You must hold the head of the screw stationary (with the screwdriver)
as you tighten the locknut or you will change the crucial pre-loaded pressure on
the spider and cone. If the screw accidentally turns as you tighten the locknut,
then you must go back to step #1 and re-calibrate the cone and spider.
6. Tighten the nut until it is snug against the pickup, and then 1/8 turn tighter.
7. Re-assemble the instrument and tune to pitch. Plug the instrument into an
amplifier and slowly turn the screw counter-clockwise until you hear a strong
signal from the pickup.
WIRING OPTIONS
Passive Pickup
NOTE: There is a network of electronic components hard-wired to the jack on
the passive Resophonic pickup. Do not remove these components; they help to
balance the pickup's bass response.
