DigiTech RP-1

This is the unit that started it all, as far as I know the very first fully functional digital multi-effect floor guitar effect processor.  This particular one was one of the first ones in the stores.  I am the original owner, it has been well cared for and even still has the plastic protector sheet still on the display glass.  It is fully functional, no problems and nothing broken on it.  It's been used on many gigs, but only a little wear on the case to show much use.  It does come with the original padded carrying case.  

It is fully programmable, or you can just use the many patches that are already programmed in it.  It has MIDI capabilities and can be used as a headphone practice unit (sounds awesome though headphones).  Even if you just want to use this as a midi foot control for your effects system, it would be worth looking at for this price!
