Just to give a few mini-reviews...
New Strat: I like it a lot more compared to the old one. The strum bar is improved, but still not "clicky." I have an easier time moving up and down the neck compared to GH guitars, and it doesn't cramp my wrist as much. The auto calibration worked like a charm too.
Mad Catz Mic: It's alright. I think I'm going to return it. Leaving out a Right Bumper nerfs the thing IMO. It's really just about the convenience. As far as sensitivity goes, I'm not a good singer, so I can't tell if it's better or worse on medium. Its probably best to wait for the next version of this thing, as 60.00 is pretty steep.
Mad Catz Bass: I was hesitant at first, but this thing is great. Nice and heavy, with good attention to detail. Playing bass the correct way is going to take some getting use to, but I welcome the new challenge. There's no whammy bar on it, but instead a whammy knob, which is really neat. Suck that it's wired, but if you have the extra cash, I say go for it.
Ion drums: The price is beastly but they really are amazing. The sensitivity on the 4 main pads is spot on. You have to hit the cymbals a little harder to register consistent hits, but it's not to bad. Also, these things are HUGE. They make the other drum sets look like crap compared to them. However, due to the extremely steep price tag, I'd recommend it for only the hardcore crowd.
