KeithBMI used to have a video demo of the LTD SR somewhere, but I can't seem to find it now.

I do remember it sounding pretty awesome, though. I thought Burgermeister did some clips, too, but I can't find those either!
FWIW, I've looked into the different LTD versions a bit. As dannybuoy mentioned, the SR has a flat midrange, but I also understand that it has the best bass response of all the versions. That'll be my pick if I decide to pick one up.
