CALIBRATION INSTRUCTIONS:
If you unscrewed the back plate on the pedal, you may have
noticed a little trimmer. Don't touch it! Your unit has come
pre-calibrated. You may decide you want to mess with this
to try to eke out more sensitivity. Ok, here's how to do it:
1) Power the unit with a 9V adapter. It's easiest this way.
2) Turn the release knob all the way counterclockwise
( ) and the sensitivity knob all the way clockwise
CCW
( ).
CW
3) Put the "Gate/Mix" switch in "Gate" mode and make sure
both stomp switches are engaged (
4) Buffer should be on and "Normal/Chop" switch should
be set to Normal.
5) All 3 LEDs should be on. If the middle LED is off, it's OK,
but then we need to fix the calibration.
6) Unscrew the bottom lid, twist that trimmer all the way
CCW. Keep an eye on that middle LED, at some point in
this process it will turn off.
7) Now, very carefully and very SLOWLY, turn that trimmer
CW. As soon as that middle LED turns on, STOP!
8) That's it! You're unit is calibrated for maximum sensitivity.
You can do steps 6 and 7 several times if you want to
make sure you have absolute maximum sensitivity out of
it. Just remember that you have to bring the trimmer all
the way CCW before you can bring it back CW.
ADDITIONAL DETAILS:
"Mix" Mode:
When in "Mix" mode, it's impossible for your guitar signal
to get into the Loop. In fact, the Loop Gate™ send jack is
grounded in this case. The purpose of "Mix" mode is to be
able to crossfade your guitar signal with audio being gener-
ated in the Loop. So, you'll need something happening in
the loop for crossfading to occur (

Using Chop While in "Mix" Mode:
Chop mode is arguably the coolest / most fun thing about this
pedal. You can still use chop even while in "Mix" mode, even
though it might seem kind of weird. The unit will go back and
forth between your guitar signal and whatever is going in the
loop.
Buffer Toggle:
A word of warning when not using the buffer: Certain ef-
fects, especially fuzz devices, may cause the sensitivity to get
loaded down and may be less reliable or predictable when
not using the buffer. The problem, of course, is that it is often
not desirable to put a buffer between your guitar and fuzz. The
best thing to do is experiment with the sensitivity knob and
your playing style to get something that works with your setup.
Also, try your fuzz with this buffer, you might like it!
Send / Receive Jack Wiring; Sidechain Capability:
The send jack and receive jacks are wired so that the send
is normal-ed to the return, so if you unplug the effects loop
the unit will operate as a standalone gate. That is to say, the
jacks are shorted together when the send/receive jacks are
unplugged. In addition, the send/receive jacks on your Loop
Gate™ are wired in a similar way as a recording console. If
you just plug into the send, the signal is not interrupted inside
(
the send is still shorted to the return
the return only, the send is left dangling dead and the original
guitar signal disappears completely from the path. This allows
for "sidechain" capability as you could plug in a different audio
source into the Loop Gate™ input and route the guitar (
) into the receive jack.
