B-52 LS-100 FEATURES
The B-52 LS-100 represents the latest in the ever expanding line of highly
acclaimed B-52 guitar amps. New, user-friendly features combined with the
latest advancements in preamp technology makes the LS-100 an outstand-
ing choice for the professional player and the weekend warrior. The clean
channel now has the innovative B-52 “Mid Cut” feature. This pushbutton
allows you to select the classic, warm vintage sound or a pristine, almost
acoustic-like tone with tons of headroom. The overdrive channels go from
moderate classic breakup to monstrous gain, totally controllable thanks to
the individual gain and master controls for each overdrive mode. The over-
drive channels now feature the new, B-52 assignable Contour control. This
allows you to preset the Contour control and have it automatically activate
on the gain channel of your choice. You can set one overdrive channel for
a punchy midrange tone with the Contour off and turn the Contour on the
other overdrive channel for a massive, totally scooped out metal tone.

HEARING DAMAGE, PROLONGED EXPOSURE TO EXCESSIVE SPL
B-52 guitar amplifiers and speakers, including the LS-100, are capable of producing sound pressure levels (SPL) sufficient to cause
permanent hearing damage to performers, production crews or people in the audience. Hearing protection devices such ear-plugs
are recommended. Caution should be taken to avoid extended SPL is excess of 90 dBA.
AMPLIFIER MODULE PRECAUTIONS
Do not attempt to service the LS-100 by yourself. Refer all servicing to a B-52 Guitar Amplification Authorized dealer. Service is
required when the LS-100 has had liquid spilled on or inside the unit, has been damaged in any way, has been exposed to rain or
moisture, does not operate normally or has been dropped.
WARNING – SHOCK HAZARD
To reduce the risk of fire or electrical shock, do not expose this unit to rain or moisture. Do not operate your LS-100 near a pool or
other standing water. Make sure all blades on the polarized power plug are fully inserted into the power source. Ensure the power
cord is not stretched, pinched or otherwise abused. Ensure the power cord is routed to avoid foot traffic. Your LS-100 amplifier
should be cleaned only with a dry cloth.

Special Features of the LS-100
Setting the effects loop send and return controls:
1) Adjust the amp to normal playing volume with nothing plugged into the effects loop.
2) Plug an effects unit in and set the return control to 12:00
3) Adjust the send control so that the volume is about the same as when the effects were not plugged. Verify this by unplugging
the effect unit to compare.
4) If, when the effects are plugged in, you notice a loss of tone or distortion, readjust the send control until the tone loss im
proves. Then readjust the return level control to, once again, match the volume before the effects were connected.
RECORD OUT:
This output provides a pre-equalized signal that closely mimics the sound of a 4 x12” cabinet. Instead of placing a microphone in
front of the speakers, simply connect this output directly into your recording or PA console. Now you have a consistent, repeatable
signal that is no longer dependent on the precise placement of a microphone.
SPECIAL NOTE: If when attempting to use the recording out, you notice excessive hum (even with the LS-100 Master volume off),
this is an indication of a “ground loop”. The solution is to use a direct box with a ground lift switch between the console input and
the LS-100 recording output.
