you won't regret it if you get one. Which model are you leaning towards? I think I've heard the TAT has the thinnest neck which would be most like the Ibanez...
it's just the regular ones, I'm pretty happy with them at the moment, I definately wouldn't change the neck pickup, that standard one sounds amazing, and if I did change the bridge pickup, I'd probably just get one of the bridge pickups from the Caparison Dellinger model, which are similar, but a bit more output, more guts overall... But for now, just the standards which are still great.
oooh, I'll be looking very hard at the Carvin 7 strings if Caparison don't get around to making a 7 string Horus... Tony MacAlpine uses one, that's good enough for me...
