Wow, this is that super rare Synton that is never seen or heard. Sounds like a version of the Fenix 1 (but much easier to play). The rarest synth from Synton, as there were only a few ever made in the 1970's! In this pristine condition, it is impossible to find. Regretfully giving it up to the next synthesist! Every feature works great! The only other one I have ever seen does not look this good or this clean... There was one on ebay in 2016 (black one) sold for 6600 Euros! Only one I have seen in the history of searching for rare synths. This one is immaculate, for a synthesizer museum collection!
