Fender Mustang Amp Controller

Control your Fender Mustang guitar amp from Stream Deck over USB. Switch presets, play hundreds of library tones, tune, and adjust amp and effect settings with Stream Deck + dials and buttons. Built for guitarists who practice, record, or stream.

Features:

Preset keys for the amp's stored presets: 24 on the Mustang I–V, shown in the amp's bank colors, or 60 on the Mustang LT25

About 400 hand-picked library presets, searchable by genre and tone, playable without overwriting your amp

Tuner key with note display and in-tune meter

Tap Tempo key that sets the delay time

Scene keys that switch effects on or off and set controls without loading a preset

Stream Deck + dials for presets, crates, amp controls, effects, and volume

Save tweaked sounds, store them in amp slots, and organize them into crates, such as set lists or favorites, with per-sound volume trims

Rigs: back up all 24 amp presets and send a new set to the amp in one step

A library page in your browser for browsing presets, crates, and rigs, assigning presets to keys, backing up your library, and importing or exporting .fuse files

Requirements:

Fender Mustang I (v1) or Mustang LT25 amp connected with a USB cable

Close other Mustang editors while using the plugin. Only one app can control the amp at a time.

Compatibility: Tested on the Mustang I (v1) and the Mustang LT25. Other Mustang models may work but haven't been tested yet. On the LT25, presets, effects, amp and effect knobs, and Tap Tempo work; the library, tuner, scenes, and Volume Knob don't yet. Support for more models is planned.

Setup tip: Plug in the amp, close other Mustang editors (like FUSE, Fender Tone, or online Mustang editing tools), and drag a Preset or Now Playing key onto your Stream Deck. Do the same with an Open Library key to browse library presets. And don't forget to add a Tuner key and drop that D 🤘

New:

LT25 support: Preset, Previous/Next Preset, Preset Knob, Now Playing (edited status/reload), Effect On/Off, Amp Knob (gain, volume, treble, middle, bass), Effect Knob, Adjust Control and Tap Tempo. Other LT models are untested. Library, tuner, scenes, Volume Knob and other unsupported actions are unavailable on LT. If it stops responding, reconnect USB or restart the plugin.

Tap Tempo key sets delay time (I–V except Multitap, plus LT).

Volume Knob dial (Stream Deck +, I–V): a volume offset across presets; press/tap resets.

Scene key sets effect on/off states and controls without loading a preset.

Store sounds in amp slots from Library; old sounds stay in My presets.

Per-entry crate volume trims.

Library backup/restore and .fuse import/export.

Movable/resizable Stream Deck dock in Library: assign presets by click or drag. Choose preset… selects a key without playing it.

Improvements:

Previous/Next Preset and Preset Knob wrap around.

Amp/Effect Knob steps: 0.1, 0.5, 1 or 2.

Adjust Control: tap to switch up/down, hold to adjust; reverses at 0/10.
