🙋🏻♂️ Welcome to SynthFreak!
Hey and thank you for visiting my shop and for your interest in this Keyboard! 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.

💲Prices
It is very important to me that my devices come into good hands! If you can't spend that much money right now, due to the current economic situation regarding the pandem.. In all of my offers, I offer the option to send me a price proposal. If you are really interested, just send me an offer, if this is possible, I will of course accept your price proposal.
⚠️INFORMATION
All my synthesizers and keyboards come from my private collection, which is constantly updated. All devices are thoroughly cleaned, disinfected and tested! Every device that is for sale is taken from my collection and already wrapped in foil to avoid dust deposits and other soiling.
📦SECURE PACKAGING
It is very important to me that you as a customer are satisfied, and that your ordered instrument is intact and in top condition arrives at you. I attach great importance to safe packaging because you never know how the parcel delivery service will handle the parcel. For this reason, I pack every instrument in a very safe way so that everything arrives undamaged and we are both satisfied. Take a look at my "SECURE PACKAGING" now! Every instrument is packed exactly this way, you can find pictures in the picture gallery.
💢Shipping during pandem.
Due to the pandem. it has become much more difficult and expensive to send parcels abroad! Since the pandem. measures change regularly, I always look for the best, fastest and safest shipping service for you so that you receive your instrument on time. With me you can be sure that you will receive your package even during the cov. pandem.
⚡Power and connection
My instruments come from the EU, so the power cable is also equipped with an EU plug. If you live in a non-EU country, it is possible to use different adapters for the power connection. It is also often possible to set the transformer to the voltage of your country, or you simply use a current transformer which is often offered on the Internet for 30-50 €.
