Please use the dedicated button for price negotiations. I am generally open to offers. This is a set of the TR-09 Rhythm Composer and the TB-03 Bass Line Synthesizer. They are in like-new condition. I have hardly used them. I was keeping them as part of my collection, but I'm selling them due to financial difficulties. I think this is a great deal. Thank you for your consideration. Please inquire about separate sales. - Model Name: TR-09 - Model Name: TB-03 - Brand: Roland - Features: Computer Control - Tone: Bass Line - Features: Rhythm Composer Thank you for looking.
