Utility Menus
Press the UTIL button to activate the Utility menus.
Press the UTIL button repeatedly to step through
each of the nine menus, listed below.
• Quick Access #1 / #2 / #3 — Use the first three Utility menus
to choose Quick Access presets. You can then access those
presets quickly from the footswitches (see Footswitches,
page 9).
• Two-Button Footswitch Mode — Use this menu to assign
functions to the two-button footswitch.
• Four-Button Footswitch Mode — Use this menu to lock
the four-button footswitch in Mode 1, Mode 2 or Mode 3.
Select "Normal" for normal, multi-mode operation. Tuner
mode is always available, even when a mode is locked.
• Memory Lock — Use the Memory Lock menu to prevent
accidental preset modifications. You will still be able to make
temporary changes to presets with Memory Lock ON, but you
won't be able to save those changes until Memory Lock is
switched OFF.
• Line Out Boost — Use the Line Out Boost menu to adjust
the output level of the Line Out jacks to accommodate the
input sensitivity of connected sound equipment.
• LCD Contrast — Use this menu to adjust the contrast of the
Mustang display.
• About This Amp — This menu displays the Firmware ver-
sion currently running on the amplifier. Use this information
to determine if an update is available for your amplifier.
Speaker Outputs
Mustang V, only
The Mustang V head amplifier provides stereo speaker
outputs that must both be connected to a stereo speaker
cabinet such as the Mustang V 412, with four 12" Celestion®
G12P Rocket 50 speakers (recommended), or two 8Ω speaker
cabinets capable of handling 75W each.

Line Outputs
These stereo XLR output jacks provide balanced, line-level
signals for connection to mixing consoles or recording
equipment. Press the GROUND LIFT switch "in" to disconnect
the ground connections (pins-1) from the XLR jacks which
may reduce line noise in some situations. Normally leave this
switch in the "out" (grounded) position.
Aux / Phones Jacks
Auxiliary Input
You can use the Auxiliary jack to input audio into your
Mustang amplifier for accompaniment. Connect the
headphone output on your CD player or MP3 player to the
AUX jack using a mini-stereo cable. Use the volume control
on your player, together with the MASTER volume knob, to
adjust the auxiliary volume level.
Phones Jack
Plug in your headphones, ear buds, or powered
speakers to enjoy the Mustang's stereo features. This
jack may also be used as a stereo recording output. The amp's
speaker is muted when the PHONES jack is used.
Effects Loop
Connect external effects devices to your Mustang amplifier
using the effects loop jacks.
Mustang IV & V
The Mustang IV & V amplifiers can accept stereo or mono
effects devices. Note that a mono-in, mono-out effect unit
will use one send and one return, and only effect one side
of the stereo image. The Mustang III amplifier only accepts
mono effects devices.
Connect the FX SEND jack(s) to the input(s) on your external
effects device and connect the FX RETURN jack(s) to the
output(s) on your effects device.
