The default Presets for the vintage amps I tried sounded like caca. After I auditioned the 3rd one I realized I was just wasting my time, stopped and wiped out the whole bank and started uploading my own.
These are presets built for use with FRFR systems; I'd suspect they may sound a little weird with a conventional cab (assuming you bypassed the CAB block since you didn't require it for your setup).
