A Modern Legend is improved with Fender Innovation

The new Fender Mustang GT Digital Amplifers are now bigger and better with the addition of built-in Wi-Fi and brand new effects.

The Worlds First Guitar Amp with WiFi!

The Fender Mustang GT Series boasts the world’s first Bluetooth and WiFi-equipped guitar amplifier, making it easy for you to download the latest updates, access Fender artist-created presets, and connect directly with a community of other creative players and music makers like yourself.

Upgraded Modeling

Seven decades worth of experience crafting inspirational tools have been employed to add new (and better) amp and effects models while making it easier to use all of this without sacrificing one iota of power. It is now easy to control a studio’s worth of authentic amp and effects models with one finger via Bluetooth and the exclusive Fender Tone app.

Packed with 21 classic amp models – everything from the renowned ’59 Bassman to modern metal – and 47 different effects, the Mustang GT-40 can easily recreate classic tones or create brand-new, never-before-heard sounds. Fender’s new algorithms yield even higher fidelity and more realistic response, along with more signal path flexibility so you can move effects anywhere in the signal chain for creative exploration. Program your sounds in the studio on the Mustang GT-40’s large, full-colour LCD display and then, with one hand, take them anywhere for the most realistic listening experience possible.

All About the Sound

Fender’s updated amp models let your instrument’s voice and the dynamic nuances of your playing come through, reacting just like the originals to your every move. Lighten your attack to “clean up” your sound or dig in to make it grunt or howl. Mustang GT-40 and its dual 6″ speakers reproduce every part of the performance with precision, as well as providing full-range output in stereo when streaming audio from your mobile device via wireless Bluetooth.

Fender Tone

Adding convenient control to the Mustang GT-40’s power is the easy-to-use Fender Tone app. Not only can you control the amp in real time with one finger, just like the originals, you can easily upgrade the amp’s capabilities, adding more power and presets without patching a single cable or plugging in a soldering iron. And, you can connect easily to the Fender Digital ecosystem for learning and sharing.

An Amp for All Uses

Coming in a nicely compact enclosure, the Mustang GT-40 digital amplifier is a perfect fit for placing on a desktop for practicing at home or recording in the studio yet powerful enough to be used on stage. The Mustang GT-40 is easy for beginning players but has enough options and power to serve even the most veteran of guitarists.
