i just got the digitech rp90 and im liking it so far but the effect i use alot is the wah and can any one give a cool riff or excersise with wah
Learn some hendrix.Try Voodoo Chile (Slight Return)
Thats the fun of the Wah pedal. Just mess around with it. Add it to your favorite songs or just improvise with it, you can find out some pretty cool stuff with it.
