The Anthem system features our patent pending Tru • Mic technology. The mic is
designed to capture the majority of your guitar’s true voice in a way that only
a microphone is capable of - plus it is amazingly feedback resistant. Our Element
under saddle pickup carries only the lowest frequencies for punch and authority. The
soundhole mounted controller has volume, mix and phase controls plus a battery
check feature so you can always be sure of your battery lifeat any gig.
This system must be installed by a professional dealer/installer. We do not provide
installation advice or support for home or hobbyist installations. Installers: please
read the instructions carefully before proceeding. We will not be responsible for any
damage to the guitar, pickup system or personal injury resulting from installation.
The Anthem’s preamp was designed to t a 4 inch soundhole and standard X braced
guitars. Before you begin a permanent installation of the complete system, check
to see if the soundhole and bracing will accommodate the preamp (see gure 1).
Note: If the Anthem’s control unit does not t in your instrument, we o er the
Anthem-SL. This scaled-down version of the Anthem with endpin preamp is preset
for optimum performance and includes a soundhole mounted remote with volume
and mic gain trim controls.

Drilling the strapjack hole
For proper installation, this jack requires a clean 1/2” hole in the tail block of the
instrument. If the guitar lacks this hole, start by placing a piece of masking tape on
the outside of the instrument over the drilling area (to avoid chipping the nish), drill
a small pilot hole in the tail block and then follow with a step drill bit.
Installing the strapjack
Remove the strap ring, retaining nut and one washer from the smaller threaded
section of the jack. There should still be one star locking washer, one at washer
and a nut remaining on the larger threaded section of 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 gure 2). 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). Asserting too much
pressure may crack the nish.
Note: to prevent rattles that the Tru • Mic will hear, secure the barrel cover against the
pinch nut. If the tail block is too thin and the barrel cover will not reach the pinch nut,
tighten the barrel cover until if ts snug. Do not over-tighten.

The bridge slot must have a clean, at surface free of debris and excess over-spray from lacquer, (sometimes left from guitar manufacturers). String balance problems
are often the result of an uneven interface between the bottom of the saddle and the saddle slot oor. Both surfaces must be completely at to give you the best
chance at a successful installation.
The depth of the saddle slot is an important factor. A tip to help determine if your slot depth is adequate is the 50/50 rule which basically says: The amount of saddle
visible above the bridge surface (with pickup installed) should be equal to or less than the amount of saddle in the slot beneath the bridge surface. An installation in
which you have a tall saddle in a very shallow slot could be the cause of problems ranging from string to string imbalance, excess feedback, and poor tone quality.
