why is everyone only focused on the Stock factory sounds when with these units you can tweak and edit the sounds and styles till the cows come home...? there's much more that can be done we already know it sounds good but a player can make it much better...but the navigation, settings, Os operation, mod wheels placement, after purchase service support, all factor into the purchase,.....you have to ask yourself is it a rehash of the SD7, how does it compare to the Pa4x/T5 etc,and of course the final questions if I don't like it can I sell it easily? & DO I REALLY NEED IT? just sayin'
