$350 · Alesis Ion analog modelling synthesizer

The condition of this synth is used (there's cosmetic scuffs), but all keys and knobs and buttons work. There are two issues with its condition. First, it *needs* a firmware update. Until it's updated, this synth suffers from a common condition of non-updated ions, it "ghost edits". Second, the master volume experiences static while adjusting the volume but is fine once adjusted and set.
