Installation Procedure
1.
Hold the UltraPure preamp in the guitar in its
desired position to check the fit. Note that
different guitars have different soundhole
bracing and in some models it may be a tight fit.
In very few cases the bracing might be arranged
so it would not allow for this type preamp, but
this is extremely rare.
2.
Install the transducers and drill the endpin hole
following the manual for the pickup installation.
3.
Apply a strip of masking tape to the edge of the
soundhole on the guitar, hold the preamp in
place and mark the position of the lower edge of
the preamp’s mounting bracket with a pencil on
the masking tape (the piece with the red tape).
4.
Unscrew the 2 screws that hold the mounting
bracket to the preamp. The nuts have been
secured to prevent falling out.
5.
Make sure the area in the guitar where the
mounting bracket will be installed, is perfectly
clean.
6.
Remove the red protective foil from the
mounting bracket, align it with the pencil mark
you did in step 3.
7.
Press the mounting bracket onto the wood at its
desired position. Make sure not to distort the
mounting bracket’s natural form when you stick
it onto the guitar! Press the bracket tightly
against the guitar top over its entire length to
ensure good bonding.
Note:
The tape will take
24 hours until the final bonding strength is
reached, but it will hold sufficiently immediately.
8.
Plug the pickup plug (2.5mm smaller diameter
plug) into the input of the ultrapure preamp. It is
located on the square gray metal box in the rear
of the preamp.
9.
Establish a precisely fitting length of the endpin
jack cable by making a loop in it, about where
the cable meets the waist of the guitar (see
overview photo, p. 1). Secure this loop with the
supplied cable tie and cut off the excess of the
cable tie.
10.
Plug the 3.5mm plug of the endpin jack cable
into the 3.5mm output jack on the back of the
preamp.
