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 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. Al-
though  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.

If the pickup does not fit to the bridge plate because the brac-
ing 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  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 A6T preamp, the AST’s lead goes away from 
the low “E” side of the bridge area and towards the upper bout 
of the guitar (see pictures). When using A6T in left-handed gui-
tars the lead of the AST should be turned around, with the red 
B-Band logo still up, so it goes the opposite way and will reach 
the preamp.

Now  mount  the  AST  to  the  top  of  the  cardboard  installation 
template at the rectangle AST area inscribed on the cardboard. 
Now put the assembly to the bridge pins, with the AST towards 
the bridge plate and check the fit. All of the AST’s active area 
must fit at the soundhole side of the bridge plate without hang-
ing over the edge of the bridge plate. make sure that there is 
enough space that the bridge pins or string ball-ends will not 
touch the AST.  

Next remove the strings, bridge pins and the saddle. If you are 
using a UST, check that it fits into the slot easily and that the 
saddle is sufficiently tight in the slot. Remove the strap button. 
Carefully enlarge the hole using 12 mm (.47”) endpin reamer or 
12 mm (.47”) wood drill bit. Smooth the edge of the hole with a 
small file or a sinking drill bit.
