Step 8: Install the Jack

Note: If you have purchased the Dusty Harp Jack Clamp, follow the included Jack Clamp instructions instead for installing

the jack and fitting the clamp on your harp.

Remove the tip nut, the retaining nut, and the outer washer from the jack

ner washer, and inner nut in place.

Reach inside the harp and carefully push the end of the jack up through the hole you drilled in the back of the harp.

Adjust the inner nut so the step to the wider threads sits about ¹⁄ ₁ ₆" (1.5mm) below the outer surface of the harp

body (see figure 9b).

Put the outer washer on the jack followed by the retaining nut

tight. The jack should be firmly held in place. If the jack is loose in the hole, loosen the retaining nut and adjust the

inner nut so that the outer washer and retaining nut can fully seat against the surface of the harp.

Place the 12mm wrench on the retaining nut. Insert the jack-tightening pin through the cross-drilled hole in the

threads of the jack. Hold the jack in position with the pin and use the 12mm wrench to firmly tighten the retaining

nut (see figure 9d).

Screw on the tip nut as tightly as you can, as there is the potential for an annoying buzz if it is not tightened prop-

erly. You can use pliers, but try not to mar the edges. If correctly installed, the end of the threaded portion of the jack

should be slightly visible in the chamfer at the end of the tip nut (see figure 9e). Your cable plug needs to be able to

make a firm connection with the jack; it should snap distinctly into place when inserted. If the threaded portion of

the jack is too far inside the tip nut, the cable plug can be stopped by the tip nut before it makes a good connection

with the jack. If this is the case, you will need to remove the tip nut, loosen the retaining nut, adjust the position of

the inner nut so that the end of the jack barrel is very slightly farther out, retighten the retaining nut and re-install

the tip nut.

Step 9: Test

Plug the pickup system into an amplifier and use the pressure stick to lightly tap the backside of the soundboard near

each pickup element to make sure each is giving a signal. You can play your harp and use the pickup safely, but avoid

moving or jostling your harp for 24 hours. The tone and signal strength will improve over the next day as the super glue

cures to full hardness.

Congratulations! Now the installation process is complete. Please call us with any questions.
