It is recommended to use gel superglue, generously applied so that the whole surface is covered. Press

firmly and hold until the glue sets up. Alternately, 3M 254 double sided tape or equivalent may be used.

Be sure the surface is clean and dry before pressing firmly into position. Using double sided tape for the

four main elements will result in slightly reduced output levels and a somewhat altered tonal balance.

Using high quality double sided tape for the feedback suppression element should work as well as glue.

For nylon string guitars with a bridge plate, mount the 4 main pickup elements and the feedback

cancelling element in the same positions relative to the saddle and strings above. It will require a little

more care to find these locations since there will typically not be string pins to use as location finders.

Mount the feedback suppression element to the far bass end of the bridge plate.

For nylon string guitars without a bridge plate, mount the 4 main pickup elements directly to the bottom

of the top plate, in the same positions relative to the saddle and strings. Mount the feedback

suppression element to the bottom of the top plate, directly underneath the far bass side of the bridge.

2. Check string to string balance

Refer to Fig. 2 for a picture of the circuit board and jumper locations.

Protect the top of the guitar with some artist tape or similar so that the circuit board assembly can

hanging out of the sound hole. Restring the guitar and bring it up to pitch.

Remove the shorting jumper.

Plug the guitar into an amplifier and check the string to string balance, listening carefully to the loudness

of each string while picking each in turn with consistent strokes. If by chance the high E is too strong, the

fourth element can be disconnected. After carefully identifying which pickup wire is connect to the 4

sensor, unsolder that wire from the circuit board. Then either remove the sensor from the bridge plate

entirely by prying it off, or just clip the wire close to the sensor and leave the unused sensor in place.
