the saddle on a belt sander until the scribe line is just above the bridge top. Finish
sanding the bottom by hand. It is best to do this against a machined flat surface with
fine sandpaper. Use a straightedge with a strong light source to inspect the flatness
of your saddle.
Insert the pickup all the way into the slot, place the saddle on top of it, and
temporarily secure it with a piece of tape. Secure the wire with a wire clip as close to
the exit hole as is practical, with a one- to two-inch service loop.
Failure to secure the wire may produce boominess and feedback. Now restring the
guitar, and plug into your amp or PA. Confirm that the EQ controls are at their default
positions and test the Element, paying careful attention to string balance. If the
sound is satisfactory, proceed to the next section. If not, read on.
String balance problems are almost always the result of an uneven interface between
the bottom of the saddle and the saddle slot. If the string balance is uneven, check
these surfaces to ensure that they are both completely flat.
Tip: A segmented packaging knife blade is a useful tool in determining the flatness
of the saddle slot. Break off enough blade segments so as much of the blade fits into
the slot as possible. Briefly use a back-and-forth scraping motion to see if the slot
bottom scrapes evenly. Any high or low spots will be readily apparent. A minor low
spot in the slot may be compensated for by shims under the pickup; however, for
gaps over .005” or multiple gaps, we recommend rerouting the slot.
The endpin jack can be permanently mounted as shown.
The Mi-Si Air Trio comes equipped with independent
volume controls for the onboard microphone and under-
saddle pickup. Simply mount the module behind the
soundhole of your guitar with the included adhesive-
backed velcro pads - either above the low E or below the
high E - wherever you prefer. This will allow you not only
to control your overall output level, but also the balance
between the microphone and pickup signals.
