I'm selling a legend among synthesizers from the late 70's early 80's! The synthesizer may be from the 70's but is very well maintained. Small optical signs of use are present, but nothing wild .. The Sk20 works perfectly and is ready for a new owner!

The SK20 adds the POLY-SYNTH SECTION: a 7-voice polyphonic synthesizer with basic filter, pitch, envelope and portamento controls. It has two (detunable) oscillators per voice, so it is well suited for thick pads. It lacks any bite and even in normal attack mode it has an envelope that is far too slow to be used for any bass or percussion sounds.

But the pads and strings you can get shine and glitter like Bowie a-la Ziggy Stardust (especially when layered with the strings area). It's like a good entry-level synthesizer. Basic and simple LFO, filters and ADSR envelopes. It has built-in sustain, and the tremolo and ensemble chorus effect also applies to this section.

I would really appreciate it if you read everything :)

📹 Video before & after the purchase
Any interested party will be happy to receive a video of the instrument on request. Pictures say more than 1000 words but a video probably even more! So that you can get a better picture of the device on offer, I offer all my interested parties a video of the device. Every buyer also gets a video of a detailed check UP before shipping. So you can look forward to your device even before it is shipped and received and you already have a first glimpse of your new instrument. If I notice during the check that something is not working properly, the device is immediately handed over to my technician for repair.

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.

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.

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 €.
