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
