I do check that thread and this one pretty regularly. I have an expectation that these units will manipulate the instrument's signal in such a way that a wider variety of tones can be achieved. Not in the sense that a Strat will sound like a Les Paul,(although that wouldn't be a disadvantage) but subtly definitive pallet of bass/mid/treble sounds with a sort of 60s/hi-fi feel.
Again, lack of experience and hero worship influences this thought.
