'Top Tier Gear' has an extremely rare and very unique looking/ sounding vintage FM synthesizer for sale. Had Fedex NOT mishandled this synthesizer during shipping, I would have considered this to be in Excellent condition however; Fedex and the person who shipped this to me were BOTH unprofessional. The synth arrived with both end keys broken ( out of track ) the right most key still plays its note everytime yet the left most key needs to be realligned better ( I DID still get that key to produce sound/ just not as easily as the furthest right key) a true shame as this synth was shown to me as working fantastic. It STILL does however; I'm sure the next owner will want to fix/ replace those 2 keys. Other than that this synth looks to be in very good physical condition and it plays/ sounds beautifully. The pitch, the modulation, the portemento, the rhythm patterns, ALL keys and functions work as they should. This is a rare piece of musical history and with replacement keys only running about $12/ per. This is STILL an amazingly awesome synth and and I've priced it accordingly. I ship fast, safe and secure. Video is of this actual unit.
