Have the 'Voodoo Labs' proctavia/octavia(something like that)pedal a listen...go for the Digitech whammy if youve got the money,but the Voodoo labs pedal is a bit less.I will safely assume you dont have and extra $2000+ laying around for an eventide harmonizer...and if you do,then poop on you!
Later! \m/
Try once,fail twice...
