First off, I am sure this thing will NOT be for everyone...it is fairly complicated to get what you are looking for (at least to me it is). BUT, it sounds incredible, which I was expecting. The thing that has surprised me is that it FEELS great to play. I was hoping for this, but not expecting it. I am not going to say the models sound exactly lik the amps they emulate because that really depends on the amps...hell 10 of the same amps in the same room sound different too! But.... they do get the vibe of most. The one that I was/am extremely disapointed in is the Powerball model. I think it sounds like crap, but maybe I haven't figured it out yet. Interestingly, the Das Metal (VH4) is one of the models I really like and I didn't like either version of the real thing I played. I am running it through my VHT 2/50/2 and Diezel cab and Voodoo Amps cab and just ordered a Carvin DCM600 to see if I can go without any tubes, but am seriously considering ordering a couple good powered monitors from one of the houses with a good return policy to try out. Again, not going to be for everyone, but this thing delivers the goods.
