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 spe-
cifically 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.
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 run-
ning parallel under the bridge. The AST should be placed so
that the AST is on the bass side of the brace running parallel
to the strings and that part of the active area of the AST, that
has the lead to the preamp, goes on the brace for the bridge.
If the brace there is too tall put the AST in front of the brace.
Please read the instructions carefully and adapt them to the
installation.
To test fit the 1470 AST in a guitar with a bridge plate, take
the cardboard installation template from the tray in the box.
Note! There is a small 4.5 mm (.18”) round and a 4.5 mm (.18”)
elongated part that both need to be punched out to make their
respected guide holes. The 4.5 mm round guide hole is for the
low “E” bridge pin and the elongated guide hole to fit at the high
“E” bridge pin inside the guitar. Peel away the protective covers
from the two adhesive dots on the cardboard. Do not peel away
the actual AST mounting adhesive protective cover yet!
The placement of the AST is important for connection to the
preamp. For the A3T preamp, the AST’s lead goes away from
the low “E” side of the bridge area and towards the upper bout
AST at classical guitar type
