A small amount of early production Fender Mustang I and Mustang II (V.1) amplifiers were manufactured with a slightly different front panel than the later units. These units had red lettering on the front panel as well as having the amp models arranged in a different order. Because of this, once the firmware has been updated using Fender FUSE, the front panel will no longer match what is displayed in Fender FUSE.
The serial model ranges affected are:
Mustang I: CGPC10006505 to CGPC10006759 except #'s 6628,6621,6756,6603,6757
Mustang II: CGPC10006760 to CGPC10007014 except #'s 7009,7010,7011,7012,7013
As a solution to this problem we have created a custom restore file for those early amps. If you have one of the aforementioned models, please follow these instructions to ensure your amp and Fender FUSE are displaying the proper Preset information.
