Not as such; it does have reverb, but it has input jacks where you can patch a synth - or I suppose you could patch a guitar into it and create vocoder effects by playing the guitar and using your mic that's obviously patched into the 550. I messed around with patching my Fantom X keyboard into it and made the grand piano sound do some vocoding stuff. Sure was interesting.
