6. PREPARING THE GUITAR FOR INSTALLATION
Please read completely before starting the actual procedure.
6.1 Test fitting AST
For test fitting 1470 AST, loosen and remove the strings from
the tuning machines.

AST Placement. See text at the following pages.
Before removing the strings and bridge pins from the bridge
check to see if the AST will fit at the bridge plate correctly. Also
at this time, clean the bridge plate surface with a moist cloth and
let dry completely.
The AST can be mounted by hand or with the supplied cardboard
installation template.
The cardboard installation template for the 1470 AST is specifi-
cally made for bridges that the saddle is at a slight angle to the
bridge pinholes. It could be that the guide is too long for the
space. If so, the template can be trimmed with scissors slightly
to accommodate this. If the template does not fit the space, even
after trimming, the pickup may be installed by hand. Although the
instructions do not specify how to do this, if you carefully read the
instructions you will be able to adapt them to perform the instal-
lation by hand. It really is not that hard or critical to install if you
are careful. If the pickup does not fit to the bridge plate because
the bracing is too close, the pickup can be mounted behind the
bridge plate at the soundboard.
For classical guitars the installation the AST is done by hand
without the guide. For most classical guitars the AST is placed
inside the guitar parallel to center brace that runs parallel to the
