LR Baggs Element Active System - Manual (Page 2)

Inspect the inside of the guitar and note the position of the braces and the
iBeam in relation to the saddle slot. Drill at either end of the slot on the side
that will enable you to avoid all braces as you penetrate the top, as shown in
figure 5. Blow out the slot with compressed air and check for remaining debris.
Important: Round the inside of the hole where it meets the bottom of the slot
with a small, sharp knife or small file to avoid pinching the pickup as the
saddle lies on it.
Feed the pickup into the slot from inside the guitar with either side up.
Inserting a toothpick or similar object through the hole from the outside is
helpful in finding the location of the hole on the inside of the guitar.
Important: The fit of the saddle in the slot is the single most important factor
in this installation. It is crucial that the bottom of the slot and the lower
surface of the saddle be flat to make even contact with the pickup. The saddle
should fit loosely enough in the slot that it can be pulled out with your
fingertips. It will then have a slight forward lean when the strings are under
tension. It is absolutely necessary to compensate for this slight lean by
sanding a tilt in the bottom of the saddle so it still sits flat on the pickup when
the strings are at tension (see figure 6). If the saddle is too tight, binds at all or
is too loose, this will have a negative effect on the string balance and output.
Set the saddle in the slot, noting how much material must be removed to
compensate for the thickness of the pickup. Sand the bottom surface of 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.

5.1 Volume wheel placement: Find a comfortable and convenient place to
affix the volume control at the edge of the sound hole -- most users will find it
best to position the unit on the side of the soundhole that will be above the
strings when playing. Clean the desired placement area completely, peel off
the adhesive backing, and stick once. Be sure that the chosen spot does not
interfere with any bracing.
5.2 Battery Bag placement: Stick the double-sided adhesive to an easily
accessible spot inside of the guitar near the preamp. Insert the battery and
battery clip into the bag. The battery can then be changed by opening the flap
on the bag and pulling out the battery.

Passive auxiliary channel: It is possible to add a mini-mic or magnetic pickup to the Element Active System. Do not use high impedance pickups
such as the iBeam.
Adding a mini-mic: To add a mini-mic, solder the hot lead to positive and the ground lead to negative of the auxiliary passive input and run both
pickup and mic down a stereo cord to a 2-channel mixer with phantom power for the mic (see figure 8). The mic will be on the ring channel.
Adding a magnetic pickup: Add a magnetic pickup the same way to the auxiliary passive channel, and run both signals down a stereo cord to a 2
channel mixer or use a stereo Y cord and two Para D.I.s. The magnetic pickup will be on the ring channel.
