Adhesive side
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 A2.2 preamp, the AST’s lead goes away from
the low “E” side of the bridge.
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.
6.2 Drilling hole for UST
For UST check the inside of the guitar to find the position of the
braces. Drill a preferably 30 - 45 degrees angled, 2.3 mm (.09”)
or 3 mm (.12”) hole (depending on the model of your B-Band
UST) for the transducer into the one end of the saddle slot. Be
careful not to damage the braces! In case you cannot make the
hole angled, because of possible damage to the braces, you can
make it straight down.
It is very important to smooth the edge of the hole using a bit
of rolled sandpaper or a small file, to avoid pinching the UST as
the saddle lies on it. For A3T preamp you must drill the hole at
the low-E string side of the slot.
6.3 Placement of A2.2 preamp
The A2.2 is placed inside the guitar at the back of the guitar
and so that you can see the preamp, and so that the input gains
controls at the top of the preamp, are accessible with a screw-
driver from the soundhole.
Be sure that the placement can be reached by both pickups and
by the output jack wire.
The A2.2 preamp is held in place with the supplied adhesive.
Once the correct place is found, clean the area with a slightly
moist cloth and attach one side of the adhesive.
6.4 Installing battery holder
Before installing the battery holder it should be checked by
