Jazz piano major here! Selling my Roland Rd-150 keyboard for $500 (was $1500 new). Plays great, and is in perfect condition other than some cosmetic scratches. I'll throw in my Behringer Ultratone k450fx amp for $50 (goes for $200 new). If you just want the amp you can have it for $100!
I'm selling this equipment because I had to bring it in my car on the way to Oberlin, due to the fact that I was on tour. Since I already have another keyboard and amp here, I don't need this set.
I've had many awesome gigs with this keyboard, so I'm hoping it finds itself in good hands. Let me know if you want to try it out!
