Great modeler. Mostly bought for the size and reputation for great high gain, mid gain, and clean amp sounds. Very configurable device. Allows you to program the foot switches in multiple ways. Can load up to 10 custom IR's. Spent a few weeks with this and the sound easily rivals software modelers like Bias FX/Bias Amp and Guitar Rig 5. Very happy with the unit. Sounds great through FRFR, PA, Headphones, or into fx return on my amp into a Marshall cab.
