I originally wanted the Digitech Whammy for it's foot switch. It would be crazy cool to work the octave like a wah. However, I agree with everyone else saying that sound-wise, the POGs are the best. However, I've looking into the Boss Harmonist and it sounds pretty cool as well. It even has the "pedal" feature, where I can raise/lower it like the Digitech. You can buy an extended foot pedal but I'm not sure what purpose it serves... wider range?
R.I.P. Ronnie James Dio. Supplied amazing music to both me and my mother.

He will be missed.
You can use an expression pedal with a pog or the boss
For pitch shifting the pog has the best sound, then whammy, then the boss
For harmonising it goes pog, boss, then whammy

IMO of course

I don't even know if it can use an expression pedal from my quick research
I was sure you could

muledit: I was thinking of the hog. With which the expression pedal can do whammy effects and filter/wah stuff
