This is a cool little Multi effects/tuner travel practice device I used when I was a road warrior for practicing along with Aebersold CD's, getting sounds quick for recording and just practicing on the bus with headphones. Lots of great sounds, built in tuner, effects, EQ, compressors etc. etc. Haven't used it in 3 years. It's in great shape. Comes with the manual and the original box. $50 shipped.
