It not the be all end all but they definetly improved it .
I hated the volume thing on the Mk1 .it is apparently fixed
I dig not like the cleans at all --The new Fender and all the cleans across the board I find much improved.
The fx were horrid as you could not adjust speed depth or most importantly the mix --Now you can edit parameters.
so really they address all my issues .
Plus they they did something I really did not expect at all the smart harmony and whammy modelling .which really does track decently and sound good.
now they are going to release a computer editor and 28 free fx..for a coverband .the amp is a good deal . IMO they did a good job
