First of all, my guitar came with stainless steel frets which doesn't seem to be listed in the description. It uses a 9v battery for the sustainiac system. With a volume, tone and 3rd knob for the intensity of the sustainiac. You then get a 2 way on/off switch and a 3 way switch for different types of sustain, such as note sustain, a mix or harmonic on it's own.
The fretwork is excellent and the floyd rose is incredibly stable, probably due to the 7 strings supporting it. Being a 26.5 inch scale, it does make things easier to play for myself. Feels weird going back to a 25.5 inch, but not in a bad way, just different!
I've always tried to avoid floyd rose guitars, but this thing is too much fun!
