Fender Mustang GT40 GT100 GT200 User Manual FIRMWARE UPDATES AND FACTORY RESTORE

As noted in the introduction, Mustang GT users should check regularly for firmware updates that improve and enhance the Mustang GT experience. To perform a Mustang GT firmware update, put the amp in WiFi update mode by pressing and holding the ENCODER for five seconds (yellow arrow in illustration below) while turning the amplifier on.

The DISPLAY WINDOW will then indicate that Mustang GT is searching for the latest firmware update, followed by indication that the firware update is downloading (see illustrations below).

When the download is complete, the DISPLAY WINDOW will then indicate that Mustang GT is applying the firmware update, followed by indication that the firware update is complete and the amp should be restarted (see illustrations below).

When performing a firmware update, the user might encounter three scenarios in which a firmware update cannot be initiated. In such cases, the DISPLAY WINDOW will indicate that Mustang GT’s WiFi connectivity is not configured, no update is available, or the amplifier update server is unreachable (see illustrations below).

In addition to the firmware update described above, Mustang GT offers several user-enabled start-up modes encompassing factory restore functions. These are described below.

RESTORE ALL: To restore the factory presets and amp settings contained in the amp’s most recent firmware update, press and hold the PRESET LAYER button (green arrow in illustration below) for five seconds while turning the amplifier on. This function is also accessible as an “Amp Settings” MENU utility button function (see page 45).

WIFI UPDATE/RESTORE ALL: To combine a firmware update and the start-up option directly above (RESTORE ALL), simultaneously press and hold the ENCODER and the PRESET LAYER button for five seconds while turning the amplifier on (blue arrow in illustration below).

FORCE UPDATE: To update Mustang GT if there is a problem with the previously described firmware update process, a “Force Update” mode can be initiated by pressing and holding the ENCODER and SIGNAL PATH LAYER button while turning the amplifier on (purple arrow in illustration below).

RECOVERY: To recover the base firmware version (displayed in “About This Amp,” see page 48) including presets, simultaneously press and hold the PRESET LAYER button and X FX utility button for five seconds while turning the amplifier on (red arrow in illustration below).
