🙋🏻‍♂️ Welcome to SynthFreak!

Hey and thank you for visiting my shop and for 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.
• 🚀 Worldwide Fastest FREE Shipping: I believe in delivering excellence to your doorstep without extra costs. Every purchase includes expedited, fully insured worldwide shipping at no additional charge, ensuring your instrument arrives as quickly and safely as possible.
• ⚡ 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 a Korg Z1, an absolute milestone in digital synthesis history from the late 1990s. While Korg dominated the era with sample-based workstations, the Z1 was their ultimate, uncompromising statement in cutting-edge DSP technology, powered by Korg’s legendary MOSS (Multi-Oscillator Synthesis System) engine—the very same technology found in the iconic OASYS and Prophecy.

Rather than relying on static recordings, the Z1 uses advanced mathematical physical modeling to simulate physical components in real time. It features 13 different oscillator models, including standard analog modeling, brass, reed, plucked string, bowed string, organ, and electric piano simulations. Because it models physical reality, it reacts organically to your playing—producing screaming leads, deep acoustic textures, crystalline pads, and complex, fluid digital textures that feel truly alive.

Technically, this Korg Z1 is in excellent operational condition. These deep digital synths require careful checking to ensure the internal digital routing and control matrices perform reliably. This unit has been thoroughly tested, and all 12 voices of polyphony turn on flawlessly. Every single rotary pot, button, the pitch/mod wheels, and the highly expressive X-Y Touchpad controller respond with perfect precision. Optically, the synthesizer is very well-preserved, exhibiting only normal, light signs of use from careful handling over the years, maintaining a magnificent studio presence.

Please note: This listing includes the Korg Z1 and the power cable.

Custom Carpenter-Built Wooden Crate: To ensure maximum safety, a custom heavy-duty wooden crate is individually crafted by a professional carpenter specifically for your instrument. Palletized Shipping: The finished wooden crate is then securely strapped onto a heavy wooden pallet. This prevents any rough handling, drops, or improper orientation during transport.

📹 Video Before & After Purchase

Any interested buyer is welcome to request a video demonstration of the instrument.

Additionally, each buyer receives a detailed functional check video before shipping, so you can see and hear your Korg Z1 running through its voice architectures, touchpad modulation, and filter configurations. If any issue is discovered during this final inspection, it is immediately corrected by our technician.
