Interesting. I wonder if the tonality has been drastically altered by them using polyphony.
From the website:
True Polyphonic Pitch Shifting and Whammy effects in a single pedal
Also looks like this thing is side-jack mounted, and surprisingly runs off DC instead of AC (although it says 1300 mA).
The one major question I would have is, what is the street price going to be on this gigantic pedal?
I'd only hope it's sub-$400, more likely in the ~$350 range, but I can dream that it were cheaper. (not that I'd be purchasing one, but a cheaper WH-4 would be pretty tempting... although I highly doubt that would happen either since the Chrome special edition whammy didn't even dent the market price of the WH-4... even though it's just a WH-4 in a shinier $50 more expensive case...)
If it's $400, you could get a Line6 M9 and have essentially the same octave effects, plus a ton of other stuff.
If it's closer to $500, the Eventide Pitchfactor far outshines it in flexibility and features.
Luckily EHX didn't try to create a pedal that you could program to use any polyphonic pitch and assign to one side or the other of an expression pedal, or they'd just be another major contender for DigiTech. (well... at least they haven't done it yet...)
New Whammy! Whammy DT!
