Drilling the strapjack hole
Drill a clean ½” hole in the tail-block for the strapjack. Remove wood shavings & dust from inside the uke.
Installing the strapjack
Remove the strap ring, retaining nut and one washer from
the end of the jack. There should still be one star locking
tail-block
washer, one at washer and a nut remaining on the jack.
Bring the jack down through the soundhole into the body
and insert it into the pre-drilled hole in the tail block. Using
the internal nut (be sure to include the at and star washers), set the proper depth that will allow the entire smaller
threaded section to protrude from the instrument (see g-
g. 1
ure 1).
With the jack in place, lay the remaining washer over the threads and attach the external retaining nut until it’s
tight. Finish by attaching the strap ring (it should cover the retaining nut and washer).

Drilling the hole
Drill a hole at the far edge of either end of the saddle slot. The diameter should be the same size as the

saddle slot and no less than 3/32”. To avoid kinking and damaging the pickup, slightly round the top edge of
the hole with an exacto blade or small le.
Installing the pickup
To make installing the pickup easier, we have included a green mono lament line for pulling the pickup
through the hole. There is a loop tied on one end to keep the line from falling into the instrument. Slip the side
without the loop down through the hole in the saddle slot and feed it up through the soundhole. Thread the
line through the hole in the guide at the end of the pickup and tie a knot to secure it (see gure 2).

After the wire and line are connected, pull up on the line above the bridge and guide the pickup into the
saddle slot. Using sharp cutters, remove the guide from the pickup just beyond the tapered section leaving a
small portion of the soldered braid intact (approximately 1/16” long) (see gure 3 on next page). Finally, lay
the pickup down in the saddle slot.

the overall height of the saddle. NOTE: The t of
the saddle is the single most important factor for
the installation. The bottom of the saddle should

Battery placement
Place the battery in an easily accessible spot with the velcro pad included. Be sure to clean the area thoroughly
before installing.
Volume wheel placement
Find a suitable location near the top inner edge of the soundhole for the volume pot. Clean the area, peel off
the backing from the adhesive and put the pot into place.
Secure all wires with the wire clips provided and re-string the uke. You are done.
