🙋🏻‍♂️ 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 an ARP Pro/DGX, a beautiful and increasingly hard-to-find vintage monophonic synthesizer from the late 1970s. The Pro/DGX is the refined successor to the famous Pro Soloist, known for its incredible expressive capabilities and the iconic "Aftertouch" (Proportional Pitch Control / Touch Sensor) that allows for stunning vibrato, wow, and brilliance control. It offers a warm, organic, and cutting analog sound that has been immortalized on countless classic records. This particular unit stands out due to its classic ARP design and reliable performance, making it especially attractive for collectors, producers, and vintage enthusiasts looking for that authentic 70s analog lead sound. Technically, this ARP Pro/DGX is in very good condition and fully operational.

All keys, preset switches, sliders, and the sensitive aftertouch mechanism have been checked and cleaned, ensuring reliable and smooth performance. Optically, the instrument shows normal signs of use consistent with its age, but remains in a very well-preserved overall condition. Its classic professional look gives it a unique and elegant vintage appearance.

Please note: this listing includes the instrument itself and the power cable. No additional accessories such as stand, legs, or case are included unless explicitly stated.
