STRAPJACK INSTALLATION
Drill a clean 1/2” hole in the tail-block for the strapjack. Remove dust & debris from inside the guitar. Remove 
the strap ring, retaining nut and one washer from the end of the jack. Bring the jack through the pre-drilled 
hole in the tail-block. Using the internal nut, set the proper 
depth that will allow the entire smaller threaded section to 
protrude from the instrument (see gure 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.  Asserting  too  much 
pressure may crack the nish.
PICKUP INSTALLATION
Connect the strapjack to the pickup with the 1/8” plug. Loosen the clamp screws on either end of the M80 until 
the clamps are open enough to accommodate the soundboard thickness. Slide the pickup into the guitar’s 
soundhole up towards the neck and tighten the screws. Secure the wire with the clips provided. Carefully 
tighten the screws until the M80 is snug. If you are concerned about the possibility of the M80 damaging your 
guitar’s nish, consider applying thin cork pads (not included) between the clamps and guitar. The clamps 
have been left unpadded to improve coupling between the pickup and guitar body. Because the M80 picks 
up body vibrations, padding could have some aect on the pickup’s responsiveness.
