    INTRODUCTION This expanded owner’s manual is a thorough user’s guide to the features and functions of the Rumble LT25 amplifier. As a complement to the Rumble LT25 Quick Start Guide that comes with each amplifier, this manual pres- ents a detailed look at the amp’s versatile features. This includes navigation and modification of the onboard presets, and comprehensive descriptions of the amplifier and effect models.

    CONTROL PANEL The Rumble LT25 top control panel consists of an INSTRUMENT INPUT, five CONTROL KNOBS, a DISPLAY WINDOW, an ENCODER wheel, four UTILITY pushbuttons, a FOOTSWITCH INPUT, an AUXILIARY INPUT (1/8”), a HEADPHONE OUTPUT (1/8”), a TAP LIGHT and a USB PORT.

  • Page 5: Presets Basics

    PRESET BASICS Rumble LT25 features 30 sequentially numbered presets. Each preset consists of an amplifier and one or more effects (or, in some cases, no effects). Note that when turning the amplifier on, the default active preset is always factory preset 01. Further, 20 additional presets are available when using the “REPLACE” feature (page 7).

    EDITING AND SAVING PRESETS Presets can be easily edited and, if desired, renamed and saved in place or saved in a different location.

Simila- ry, various effects controls can be adjusted, or effects can be removed from or added to a preset.
