How do I restore the factory Preset data on my Fender® Mustang™ and Fender® Bronco™ 40 amplifier?
The Fender Mustang series and Bronco 40 amps feature a Preset Restore function that can be used to restore all Preset data back to factory settings. To access this feature, turn off the amp, then turn the amp back on while holding the Exit button. The amp will briefly light both the Save and Exit buttons. Once they are no longer lit, the restore is complete. Please be sure to back up any data (custom Presets) that you have created prior to performing this operation as all old data will be overwritten with the Restore.
