By necessity, I had to become a Fender Mustang II/III programmer. Those amps came with the available preset positions already loaded with Fender's creations. Those Fender-created presets are included primarily to showcase what the amp's capable of, but most of them sounded like something I'd never use (esp on the II - the III has a few nice modified cleans).
If the GTX is similar, then the Fender presets can be overwritten with your own (or those created by others), saved back over the original positions. You should be able to restore the factory presets per the process in the Manual.
