problem is due to unequal pressure distribution, not bad me-
chanical contact. In this case, add the paper underneath the
louder strings. Try this as the last choice because it is very time
consuming and not so efficient.

tight that you cannot pull it away with your fingers.
• Check string angles behind the saddle. They should be about
the same behind every string. If the angle is too low, the string
will not put enough pressure on the transducer and that may
cause balance problems - usually higher output from the cor-
responding string. To deepen the angle, you can, for example,
file a wedge-shaped groove on the bridge pinhole so that
the string will have deeper angle behind the saddle (see the
next picture).
• On some instruments the outer most strings are too close to
the edge of the saddle, causing balance problems to these
strings. It may happen that the E string at the end of the UST
does not come as loud as other strings. In this case, make
another, shallow hole (not all the way through) at that end of
the saddle cavity and move the pickup so the tip of the UST
goes in the hole. If nothing else helps, you should machine the
saddle slot longer and use a new longer saddle.
• Balance problems may also occur with some string sets, for
example with classical guitars the G-string may cause prob-
lems.
10.7 If all things mentioned above are correct, and there still
is a balance problem, you should try the following tricks:
• The easiest way is to install a spacer, made of soft wood,
underneath the saddle or underneath the UST. The proper
thickness is 0.5 - 0.8 mm (.02” - .03”). This will cure imbal-
ance problems effectively.
• A very efficient way is to make the saddle more flexible by
modifying it, for example see picture below. Even more ef-
ficient 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. By making the saddle flexible, these problems can
be greatly avoided.
• If anything else does not help, you can try to add one or two
layers of ordinary letter paper under the saddle, underneath
the quieter strings. This will cause a better mechanical contact
between the saddle and the UST and thus increase the volume.
If the volume decreases when adding the paper, the balance
