I had two and loved them (both for free, big cock up on Music YO's side). Probably the nicest 5 strings i had played up to that point. I traded the second one for a 4 string Honer but didn't keep it long. Nice as it was i just didn't get on with it, plus it was active and i wasnt too keen on that. I felt the passive EMG's sounded nicer.
Tone wise i was very happy with the XT-25, i quite like the EMG Selects. Ive still got a white 4 string Spirit XZ2, (the one with the conventional body shape) and that too has the EMG select's and it sounds very nice.
