As a small business, I set pricing higher on Reverb than I would on a direct sale basis. You can save money and support a small business by purchasing through them directly.

Fully functional and in excellent condition for its age.

The OBXA synthesizer is synonymous with music from Prince, Van Halen and even modern legends such as J3PO and Matt Jamiroquai Johnson. The OB-Xa is a precursor to the legendary OB-8. I also have a fully restored OB8 for sale, please check my other listings to check it out :)

Comes with a high quality copy of the original owners manual.
