"ARP Avatar synthesizer. Only 300 were ever produced. Famously brought down the ARP company due to the failure of the guitar controlling section (never tested in this example, pickup not included). It's essentially a cv / gate controlled (keyboardless) Odyssey.

It's had a recent service from Synth Prof where all the sliders and circuits were cleaned, new caps, portomento engaged (previously only for the guitar section), and the 4075 filter range extended to 28khz (putting it more in line with an ARP 2600). The pulse width faders seem to still be a bit crackly but could be replaced (i decided against it) easily if required (it's not a feature you tend to tweak on the fly). On the whole the faders are on the stiffer end of the spectrum but to me that's preferable to overly loose.. it's not an issue. In great cosmetic condition, only a couple of scratches here and there. Generally the unit is in excellent condition, especially considering it's 35 years old! Collection (North London) would be preferred but can ship.. please enquire about international shipping."
