It may be a cliche but having expensive, great sounding gear wont make you play any better, though it might make you want to play mor. If you are a accomplished musician the gear you use will augment your playing. I don't know how many times Ive heard people talk endlessly about their pro setup, blast decent gear, and then proceed to play gratingly poor quality music out of it. I'm not going to say that you can make a 30w spider III sound like a Top Hat, Fender Twin, 5150. But music comes first from the brain and hands, everything else makes that sound more how you envision it. So, sorry if I'm speaking in platitudes.
