This is a Zoom 505 multi-effects processor and guitar tuner. It has 24 different result and has several settings and functions. Great pedal for the player wishing to make a wide variety of noises without spending for all the specific pedals, or if you 'd like to experiment to see exactly what's out there. Delay noises in the U2 field, harmonic POG sounds like Jack White, Reverbs, phasers and all kinds other sounds. E-mail me if you're interested, thanks.
