🙋🏻‍♂️Welcome and Foreword

Hello and welcome to my Reverb Shop!

Thank you for your interest in this listing. Every instrument I offer comes from my private collection and is treated with great care and respect. Each instrument is thoroughly checked and tested to ensure full functionality and excellent condition. Before any instrument is listed for sale, it goes through a professional multi-stage inspection by our technician. Only after successfully passing all functional and visual checks is it approved for listing.

I am aware that my prices may be above average, but this reflects my commitment to transparency, careful preparation, and customer satisfaction. Packaging alone takes 2–4 hours, with multiple layers of protection to ensure safe and worry-free transport. Quality — both of the instruments and my work — is my top priority. I am always available to answer questions and ensure a smooth buying experience.

Enjoy reading the description.

🎹 Information about the Item for Sale

I am offering an absolute crown jewel of analog polyphonic synthesis: the Oberheim Matrix-12. This is not just a synthesizer; it is a legendary 12-voice programming powerhouse that represents the absolute peak of Oberheim's engineering, famous for its unmatched routing flexibility and lush, massive analog architecture.

This particular unit stands out for its exceptional condition and distinct heritage:

• Pristine & Untouched Originality: Unlike many vintage units, this Matrix-12 has seen very little use and spent most of its life protected inside a hard case. It remains completely original with zero improvised repairs or tinkered electronics—making it an exceptional, high-value investment piece.
• The Coveted US Version: This is the highly desirable, original US-built model. It features significantly better build quality than the later Japanese version, including beautiful wooden side panels, superior tactile buttons, and a safer, more robust internal layout with separate circuit boards for the power supply and voices.
• Thoroughly Detailed: The entire instrument has been meticulously dusted, cleaned, and disinfected on the outside. Internally, all controls, potentiometers, IC components, and contacts have been cleaned to ensure reliable operation.

Note on Future-Proofing: While the synth is currently fully operational in its authentic original state, a complete electronic refurbishment can be carried out by our technician for an additional charge upon request, giving you total peace of mind for the next 30 years.

Please note: This listing includes the US-version Oberheim Matrix-12 and the power cable, no Hardcase.
