by a professional qualified guitar craftsman or technician. Some installations require a high knowledge about woodworking and guitar structure. When doing any drilling, sawing, cutting or routing at the guitar, be sure to secure the guitar so it will not move when doing such work. B-BAND LTD AND B-BAND, INC.

3. OVERVIEW OF A5T PREAMP - Small dress washer - Lock washer - Large dress washer - Large hex nut • 1 pc battery holder with adhesive • 1 pc battery cord harness (length 15 cm / 5.90”) • 2 pcs wire clips • 1 pc instructions and user guide All B-Band A-series preamps are designed to give optimum performance with B-Band UST and AST transducers. The main criterion in designing these preamps was to deliver studio quality and user-friendly electronics to the diverse needs of acoustic instrument musicians.
The cardboard installation template for the 1470 AST is specifically 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.
.3 Making holes for A5T preamp Find a good position for the preamp at the side of the guitar. Be sure that the position is so, that when the holes are drilled that the holes, and the preamp structure, do not interfere with the any of the guitar braces or supports. For this installation it is very important to check inside the guitar body that there is enough clearance for the preamp at the side between the soundboard and the back of the guitar.
6.4 Installing battery holder Before installing the battery holder it should be checked by inserting a 9-volt battery in and out of it to learn how it works. Once this is checked, find a convenient place inside the guitar where the battery holder can be reached and that there is good access to the snap. Also check that it is in a place that the battery can be put in and out easily. Recommended places are at the neck block or at the back of the guitar.
the extra cord as a “coil” in some of the clamps if necessary. 8. Installing the preamp. For the next portion of the installation, be careful not to catch the pickup on anything as you work; inadvertent tugging may cause damage to the transducers or pull the connectors off the pin headers at the preamp. 9. INSTALLING THE TRANSDUCER If installing UST, do it now. Thread the B-Band UST up from inside the guitar through the hole in the saddle slot.
system will work but it will buzz. • Check that the connectors are inserted correctly onto their pin headers at the preamp. 10.3 Resonance or distortion with some played notes. There are a couple places where a resonance can typically occur with some notes, causing distorted-sounding output. First, check that the lead portion of the transducer to the preamp is not touching anything and that the battery or output wires are not loose and thus cause resonance.
is 0.5 - 0.8 mm (.02” - .03”). This will cure imbalance problems effectively. • A very efficient way is to make the saddle more flexible by modifying it, for example see picture below. Even more efficient it is to cut the saddle into six separate pieces, or to cut it almost through between the strings but leave just a small portion on the bottom side of the saddle, i.e. cut it from the bottom towards the top. • Most of the balance problems are due the fact that the guitar top lives.

Once you experiment with the settings of these controls you will find more about how they work. The BASS, MID, TREB, and PRES slider controls are a 4-band equalizer for controlling tone. 8. PHASE (PHASE BUTTON) The BASS and PRES (presence) tone controls are normal boost / cut shelving controls.
