General notice and disclaimer
I am a free time music producer and fanatic gear enthousiast. For over 30 years I expanded my private studio to an enormous playground of fun. I am the first owner of the pieces I put here for sale or I bought them in great condition through the decades on the used market, never saving money on finding the best possible physical and technical state. Of course these are vintage items, so it can happen that there are some touch-ups or imperfections on the sliders/buttons/knobs by the time of sale, only global functions are tested to work before shipping out. This item is sold as is, so no warranty of any kind and no possibility to return this gear. Local pick-up is preferred to avoid any risk on damage or lost during shipping, in that case contact me before buying. Shipping is only offered at your own risk. Will be shipped FAST & VERY WELL PACKED, like delicate vintage gear deserves and I would like to receive a package myself. I will put maximum effort in getting the synth safe at your doorstep and can on request update you with pictures of the package and the damping protection used for you to approve. Any import or tax duty is for the buyer and depends on the country you live in.
