Korg MS20 Blackboard - LESS THAN 30 Pcs - ✅ Extremely Rare Education Model Synthesizer✅ Authentic MS-20 Analog Circuitry ✅ Fully Checked & Cleaned ✅ The Holy Grail of Vintage Synthesis ✅ Worldwide Shipping

🙋🏻‍♂️ Welcome to SynthFreak!

Hey and thank you for visiting! I appreciate your interest in this synthesizer. Every instrument in my shop comes from my private collection and is treated with the highest level of care. My mission is simple: you receive a vintage instrument that performs flawlessly, not a "fixer-upper."

Before any item is listed, it undergoes a rigorous, multi-stage inspection by our technician. I know my prices reflect a premium compared to "as-is" listings, but this is a deliberate choice. When you buy from me, you are investing in a fully verified, professionally serviced, and risk-free collector’s item that is ready for the studio the moment you plug it in. You avoid the hidden repair bills and frustration that often accompany cheaper, unverified gear.

💎 Why You Invest in Quality

My pricing directly reflects the extensive time, technical expertise, and premium materials required to deliver an investment-grade instrument. Here is exactly what is included in your purchase:

• 🛡️ Double Technical Verification: Every instrument undergoes a comprehensive checkup before being listed. To guarantee perfection, the entire unit is tested again right before it is packed. Any component replacement, calibration, or display upgrade is handled by specialists so you receive a turn-key, flawless instrument.
• 📦 Premium Custom Packaging: Vintage electronics are fragile and irreplaceable. To ensure 100% safety during international transit, we do not use standard shipping methods. We spend hours custom-building heavy-duty, multi-layered packaging or bespoke wooden crates. This professional-grade preparation guarantees that your investment arrives in the exact condition described.
• ⚡ Power & Global Connectivity: My instruments are configured for EU 230V. If requested, I can perform a free internal voltage conversion where technically possible. If not, I recommend a high-quality external step-up transformer (approx. $50). This is the preferred, risk-free solution for 90% of my international customers, allowing you to power multiple EU-spec devices simultaneously without compromise.
• 📑 Customs & Import Optimization: International shipping often brings unexpected financial burdens. Our dedicated logistics team reviews each shipment individually to prepare customs declarations strategically. This compliant, professional approach helps minimize or entirely avoid unnecessary import fees and taxes for you.
• ✅ Transparency & Peace of Mind: I document the entire process and prioritize full professional transparency. You avoid the hidden risks, dirty interiors, and immediate repair costs that often come with cheaper 'as-is' listings from private sellers.

🎹 Information about the Item for Sale

I am offering one of the most mythical and elusive synthesizers in the history of electronic music: the Korg MS-20 "Blackboard". This is not merely a synthesizer; it is a profound piece of musical history. Originally conceived for educational purposes, the "Blackboard" or "Education" version was designed to be hung on a wall like a school chalkboard.

A True Rarity: This instrument is legendary among collectors. While Korg did not produce these as part of a regular series, historical sources and expert consensus indicate that only about 40 units were produced. Other reports suggest that approximately 30 units were allocated to international distributors, while even larger variants featuring integrated speakers were likely limited to only a handful of examples. Given their specialized use in music classes and Korg's synthesizer school in Tokyo, it is widely believed that only a very small number of these units remain worldwide in fully functional condition.

The Korg MS-20 Blackboard delivers the exact same legendary sound as the standard MS-20, while offering a unique physical design:

• Legendary Analog Circuitry: Internally, the circuit matches the standard MS-20 perfectly, providing the same high-quality, full-scale analog synthesis.
• Iconic Filter Design: Featuring the classic MS-20 filter topology—renowned for its screaming resonance, self-oscillation, and distinct "dirty" analog texture.
• Semi-Modular Patch Matrix: The iconic patch panel allows for limitless signal routing, enabling you to create complex, evolving textures and aggressive modulation.
• Unique Education-Focused Design: These units were designed with removable keyboards for maximum flexibility in classroom settings.

Technically, this Korg MS-20 Blackboard is in excellent operational condition. We understand that instruments of this caliber and vintage require absolute precision in maintenance. This unit has been meticulously serviced and completely verified by our technician. The patch points have been tested for perfect signal continuity, the oscillators are stable, and the filter response is sharp and responsive. Optically, it is a stunning historical artifact, preserved with the care such an extreme rarity deserves.
