4.1. UST (Under-Saddle Transducer)
From an operational point of view, it is important that the angle of
the strings behind the saddle is correct. An angle of 30 - 45 is ideal.
If some of the strings (or all) don’t press on the saddle with enough
force, balance problems may occur. The angle of the strings behind
the saddle should be about the same on all the strings. Sometimes
higher-pitched strings have milder angle than the lower ones. Talk to
a guitar technician about this if there are any questions.
A good contact between the B-Band UST and the saddle is needed
underneath every string to achieve good string-to-string balance.
For this to occur, the bottom of the saddle slot and the bottom of the
saddle itself must be absolutely flat. Also, the bottom of the saddle
slot should be free of debris. If this is not the case, some of the strings
may sound louder or quieter than others. Louder strings may even
cause feedback problems.
The saddle should fit in tight. If you are able to easily pull the saddle
out of its slot with your fingers, it is too loose.
The B-Band UST is so thin (0.4 mm / .018”) that it practically does
not increase the height of the saddle when installed. The depth of the
saddle slot should, however, be deep enough to prevent the saddle
from tilting forward when the strings are tightened. For the same
reason, the saddle must fit tight in the slot. A tilted saddle does not
press a large enough area of the transducer satisfactorily. It may be
necessary to compensate for the forward tilt by sanding the bottom
of the saddle oblique. If you have had a piezo-electric transducer in
your instrument, we recommend you to remove it and replace the
saddle with a properly sized saddle. Another possibility is to install a
suitable wooden spacer underneath the saddle.
In some guitars the saddle can be so narrow that even the 2.2 mm
/ 3/32” wide B-Band UST does not fit in. In such cases, the slot has
to be made wider and the saddle has to be replaced with a wider
type. In other guitars, the saddle might be an adjustable-height type
or there could be a separate saddle piece for each string. In these
cases it may be necessary to fill and reroute the saddle slot and make
a new, proper size saddle.
