🙋🏻‍♂️ 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 the absolute top-of-the-line flagship of Yamaha's classic multi-keyboard line: the Yamaha SK50D. Released in the late 1970s, this massive, dual-manual instrument is not just a synthesizer—it is a complete analog symphonic ensemble housed in a beautiful, heavy-duty wooden casing. It was built for professionals who needed an entire keyboard rig consolidated into a single, no-compromise instrument.

The SK50D is legendary because it contains four independent, parallel analog sound engines that can be layered, split, and mixed across its two 61-note manuals:

• The Organ Section: A full drawbar-style combo organ with a majestic, warm transistor character and a brilliant built-in rotary speaker simulator.
• The String Section: Rich, lush, and velvety 70s ensemble strings with dedicated attack and release controls.
• The Poly-Synth Section: A gorgeous polyphonic synthesizer with its own analog VCF filter, envelope controls, and classic Yamaha warmth.
• The Solo Synth Section: A dedicated monophonic lead synthesizer preset section (complete with a touch-sensitive aftertouch system on the upper manual) for cutting through any mix.

Technically, this Yamaha SK50D is in excellent operational condition. Anyone familiar with these complex multi-keyboards knows that maintaining their massive internal voice routing can be difficult—this unit has been thoroughly checked. All drawbars, sliders, rocker tabs, and internal contacts have been cleaned and tested. Optically, the keyboard is very well-preserved, showcasing that unmistakable, commanding vintage look with its beautiful wooden side panels showing only minimal, normal signs of use consistent with its history.

Please note: This listing includes the Yamaha SK50D and the power cable.
