This is a sleeper for some reason. Maybe because it's misunderstood. For me, the stereo FX loop and double tracking feature make this a no-brainer. This is not a modeller people! While it has a poweramp simulation and also an IR loader ), it doesn't have a preamp simulation. So, to unlock its full potential, it should be used in conjunction with a preamp (pedal). The included IRs are fine especially for live gigs, but they can be changed anytime. The new design is killer... did not like the copper version too much.
