I've been wondering how good a harmonizing pedal would be.Can they really make it sound like two guitars or what? Also whats an average price and the best brand?
Can they sound like something from Bullet for my valentine, or avenged sevenfold? Thanks.
Average price? $150.

Best ever? Either the Electroharmonix POG (Polyphonic Octave Genarator; soemthing like $300) or the Digitech Whammy ($200)
