4.2 Volume control:
Yes.
4.3 Replacing the battery:
The battery life of the M1 Active is
a very long 1000 hours, or about 250 gigs. If you’re plugged in
20 hours a week, you’ll need to replace your battery once a year.
If your battery is going dead you will start to hear some distortion.
From the time you hear audible distortion until it’s too late, you
have several gigs to replace the battery. Press on the center tab
over the battery to dislodge the battery. You may need to use a
pencil or other tool to press the tab. Lift the battery out from the
slots in the side of the pickup, then slide and snap a new one in.
Observe polarity. You should be able to read the CR2032 and the
“+” designator when the battery is properly installed.
These batteries are available at all large drugstores, and some-
times at supermarkets.
4.4 Experimenting with pole piece heights:
The pole pieces
on the M1 Active are preset (for bronze acoustic strings ), but this
is just a starting place. They are adjustable with the 3/32” Allen
wrench to obtain the optimum balance and tone. The height of
the pole pieces relative to the strings will have a profound e
ff
ect
on the sound and balance of the pickup. Raising the pole pieces
will increase the output of the strings; lowering them will decrease
the output. For the most powerful and articulate sound, we rec-
ommend setting the pole pieces closer to the strings. However, if
they are too close, they will interfere with the strings’ movement
and produce a percussive clacking noise. Lowering the pole piec-
es will de-emphasize the strings and emphasize the body sound.
We have provided two additional 3/4” pole pieces for use in the
B and little E string positions with nickel or electric guitar strings,
and one spare 3/8” pole piece for use with acoustic sets that have
an unwound “G” string.
