It's an 8/10 amp sim (which is a high score) but then fed into an impulse loader. Nothing new to market, certainly not worth $89, especially when TSE x50 mops the floor with it at 50 € (same price?) and S-Gear for $10 more with 4 more amps, and more cabinet options, and industry leading quality!
The only way they could salvage their unique selling point was if they put up a null test with an actual mic'd amp (that it was modelled after) then I could probably get on board.
Tough, but true.
