This expanded owner’s manual is a thorough user’s guide to the features and functions of the Mustang LT25
amplier.
As a complement to the Mustang LT25 Quick Start Guide that comes with each amplier, this manual presents a detailed look at the amp’s versatile features. This includes navigation and modication of the onboard
presets, and comprehensive descriptions of the amplier and eect models. It also includes illustrated stepby-step instructions for using Mustang LT25’s onboard tuner, footswitch, USB port and other functions.
While this expanded manual presents the most current version of the amplier, also check back for updated
manual versions that will serve as even more helpful guides as Mustang LT25 and its capabilities evolve.
Be sure to check fender.com/rmware/support regularly for rmware updates that improve and enhance the
Mustang LT25 experience.

EDITING AND SAVING PRESETS
Presets can be easily edited and, if desired, renamed and saved in place or saved in a dierent location. The
controls of each amplier type can be adjusted, or an amp model can be replaced with a dierent one. Similary, various eects controls can be adjusted, or eects can be removed from or added to a preset.
When a preset is active, the box containing its number is blue, indicating that no edits have been made. Once
an edit is made, the box containing the preset number turns red and the preset title screen will read “UNSAVED”. When edits are saved, the preset number box returns to blue and the “UNSAVED” title clears.
ACCESSING PRESET CONTENTS
To access the contents of a preset, press the ENCODER. From the top down, the DISPLAY WINDOW will then
show the number and name of the preset, the amplier type in use, and four boxes that organize the eects
used for that preset (if any). These eects category boxes are labeled STOMP (stompbox), MOD (modulation),
DELAY and REV (reverb). When rst accessing preset contents, the preset name and amplier type are highlighted in blue:

IMPORTANT: If edited amp control settings are not saved, the preset will revert to its original amp control
settings when returning to the preset after leaving it, or when turning the amplier o and back on again. To
save edited amp control settings, press the SAVE utility button and use the ENCODER to scroll to one of three
options—SAVE, SAVE AS or REPLACE. Each is detailed below.
SAVE: Keeps an edited preset in the same location with the same name. To do this, press the SAVE utility
button and use the ENCODER to scroll to “SAVE”. Press the SAVE utility button again or press the ENCODER. A
brief “PRESET SAVED!” screen will then ash before returning to the original preset screen:

SAVE AS: Enables saving an edited preset in a dierent position, with or without a dierent name. To do this, press
the SAVE utility button and use the ENCODER to scroll to “SAVE AS”. Press the ENCODER to access a “CHOOSE SLOT”
list of locations where the preset can be moved. Select a new location by turning and pressing the ENCODER:

NOTE: When using “SAVE AS”, note that a preset can be moved to a dierent position even if no edits have been made.
Also note that saving a preset to a dierent location permanently deletes the previous contents of the new location.
Whether renaming the preset or not when using “SAVE AS”, a name must be entered by pressing the ENCODER to activate a cursor, then spelling out the name by turning and pressing the ENCODER to scroll through
and select characters. All characters can be cleared by using the ENCODER to scroll to and select “CLEAR ALL”.
When name entry is completed for the new location, save it by pressing the SAVE utility button or by using
the ENCODER to scroll to and select “SAVE”. A brief “PRESET SAVED!” screen will then ash before returning to

automatically be highlighted. Press the ENCODER again to see a list of controls for the amp model in use; the
name of the amp model appears at the top of this list.
Press the ENCODER once more to activate the amplier replacement function; the box surrounding the amp

REPLACING, ADDING AND DELETING EFFECTS
As noted, each of the four eect category boxes can contain one eect. If an eect is present, it can be replaced with another eect in that category, or it can be deleted. If no eect is present, one can be added (see

SETTING DELAY TIMES WITH THE TAP BUTTON
There are two ways to set delay times for eects in Mustang LT25’s “DELAY” eects category box. The rst
way is to use the “Editing and Saving Eects Control Settings” instructions found on page 9, using the ENCODER to scroll to, select and adjust individual eect settings, including delay time.
The second way is to use Mustang LT25’s TAP utility button (yellow arrow). If a preset includes a delay eect, the
TAP LIGHT (green arrow) ashes in time with that eect’s default delay time. This time setting can be modied
by tapping the TAP utility button two or more times at the desired tempo, regardless of what screen is shown
in the DISPLAY WINDOW:
IMPORTANT: If an edited delay time is not saved, the eect will revert to its original delay time when returning to the preset after leaving it, or when turning the amplier o and back on again. To save an edited delay
time, follow the SAVE, SAVE AS or REPLACE instructions on pages 6 and 7.

AUXILIARY INPUT AND HEADPHONE OUTPUT
The Mustang LT25 control panel features two 1/8”-inch jacks: an
auxiliary input for connecting external mobile/audio devices and
an output for convenient headphone use.
Note that when using the auxiliary input, volume levels for external devices are set using volume controls on the external devices
themselves (the amp’s volume controls are for overall volume
level only and do not aect individual volume of external devices
connected to the auxiliary input jack). Also note that when headphones are plugged in, speaker output is muted.
USB PORT
The Mustang LT25 control panel features a USB port for audio recording. Using a micro USB
cable (not included), connect a computer with recording software to this port. No external
driver is needed to connect to an Apple computer. To connect to a Windows-based computer, the user must download the ASIO driver setup with Fender Mustang device, available at
www.fender.com/support/articles/fender-universal-asio-drive.
Note that although the USB port and the auxiliary input can be used simultaneously,
the USB port cannot be used to record a signal from the auxiliary input.
When recording using the USB port, a gain control is located in the SETTINGS menu function (page 18). To access and use this gain control, press the MENU utility button and use the ENCODER to scroll
to and select SETTINGS; “USB GAIN” will automatically be highlighted. Press the ENCODER on “USB GAIN” to
select it; the surrounding box will turn from blue to red:
