INTRODUCTION

This expanded owner’s manual is a thorough user’s guide to the features and functions of the Rumble LT25

amplier.

As a complement to the Rumble LT25 Quick Start Guide that comes with each amplier, this manual pres-

ents a detailed look at the amp’s versatile features. This includes navigation and modication of the onboard

presets, and comprehensive descriptions of the amplier and eect models. It also includes illustrated step-

by-step instructions for using Rumble LT25’s onboard tuner, footswitch, USB port and other functions.

While this expanded manual presents the most current version of the amplier, also check back for updated

manual versions that will serve as even more helpful guides as Rumble LT25 and its capabilities evolve.

Be sure to check fender.com/rmware/support regularly for rmware updates that improve and enhance the

Rumble LT25 experience.

EDITING AND SAVING PRESETS

Presets can be easily edited and, if desired, renamed and saved in place or saved in a dierent location. The

controls of each amplier type can be adjusted, or an amp model can be replaced with a dierent one. Simila-

ry, various eects controls can be adjusted, or eects 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“UN-

SAVED”. 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 amplier type in use, and four boxes that organize the eects

used for that preset (if any). These eects category boxes are labeled STOMP (stompbox), MOD (modulation),

EQ and DELAY. When rst accessing preset contents, the preset name and amplier type are highlighted in blue:

Select the amp model or one of the eects category boxes by turning and pressing the ENCODER. The active

selection is then highlighted in blue:

EDITING AND SAVING AMPLIFIER CONTROL SETTINGS

To edit and save individual control settings of a preset’s amplier model, rst select the amp model by press-

ing the ENCODER on it. The DISPLAY WINDOW will then show a list of controls for the amp model in use:

There are two ways to adjust an amp control knob setting. A control parameter that corresponds to an actual

physical knob on the control panel can be adjusted simply by turning the physical control knob until the

desired value is reached in the DISPLAY WINDOW. In the example below, the amp model’s MIDDLE setting is

adjusted by turning the physical MIDDLE control knob on the control panel:

Alternately, select a control parameter by turning and pressing the ENCODER; its surrounding box will turn

from blue to red:

The control can then be adjusted by turning the ENCODER or by turning a corresponding physical control

knob on the control panel (if present*):

At this point, press the ENCODER or the BACK utility button (green arrow) to accept the adjusted control val-

ues. Pressing BACK returns the user to the preset contents screen; pressing the ENCODER lets the user contin-

ue making controls setting changes, and the box surrounding the control setting will return to blue. When

control setting edits are complete, press the SAVE utility button to save the changes to the preset.

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 amplier 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 dierent position, with or without a dierent 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 dierent position even if no edits have been made.

Also note that saving a preset to a dierent 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 ENCOD-

ER 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

the original preset screen:

REPLACE: Any existing preset can be replaced with another by pressing the SAVE utility button, using the

ENCODER to scroll to and select “REPLACE”and choosing from 50 replacement presets (the 30 factory pre-

sets, plus 20 additional presets listed on page 3). After selecting “REPLACE”, use the ENCODER to scroll to any

of the 50 available presets; each one is automatically “previewed”so the user can hear the sound before the

preset is loaded. Press the ENCODER to select the preset, conrm it by using the ENCODER to scroll to and

select “NO CANCEL” or “YES REPLACE” (not shown) and save and save it in the chosen slot:

CHANGING THE AMPLIFIER MODEL IN A PRESET

The amplier model in a preset can be replaced with another one (see list of Rumble LT25 amplier models on

page 8). To do this, acess the contents of a preset by pressing the ENCODER on it; the amp model will au-

tomatically 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 amplier replacement function; the box surrounding the amp

name will turn from blue to red, and white arrows will bracket the amp name. Turn the ENCODER to scroll to a

new amp model. Press the ENCODER to accept the amp model change, after which the box surrounding the

amp name will return to blue; or press the BACK utility button (green arrow) to accept the amp model change

and return to the preset contents screen:

IMPORTANT: If an amplier replacement is not saved, the preset will revert to its original amp type when re-

turning to the preset after leaving it, or when turning the amplier o and back on again. To save a preset amp

replacement, follow the SAVE, SAVE AS or REPLACE instructions on page 6 and at the top of this page.
