but lets face it if you're at a level where u can make use of equipment then you're probably willing to invest money in it. Granted I won't be buying a tube amp in the near future, mainly because i like my guitar to be great rather then my amp (half the time it's just PA systems anyways) so i invest money in guitars instead. And trannies are only just getting as good as tube amps, so I expect USB guitars to take time to replicate the feel and tone and just the feeling of guitars in general.
