6. PREPARING THE GUITAR FOR INSTALLATION
Please read completely before starting the actual procedure.
6.1 Test fitting AST
For test fitting 1470 AST (if applicable), loosen and remove the
strings from the tuning machines.
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 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 may also be that the guide is too long for
the space. If so, the template can be trimmed with scissors
slightly to accommodate this. If in case the template still does
not work the transducer 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
installation by hand. It really is not that hard or critical to install
if you are careful.
Alternative AST installation for steel string guitars: Some guitars
have smaller a bridge plate than others and the AST may be too
large to fit in front of the pins. In this case the AST can be installed
behind the bridge pins. If the bridge plate does not extend enough
behind the pins, it can be installed on the top of the guitar, right
next to the bridge plate. When installed behind the bridge pins
you will hear more of the "top" of the guitar when the balance
is turned to UST / AST XOM position. This may be desirable for
any steel string installation.
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
strings on the bass strings side at the area between the bridge
and soundhole. Sometimes there is also a flat brace running
