Alesis Ion in excellent condition. This was my first real synth, I'm the original owner (purchased around 2003) and it never left the bedroom of my non-smoking household. Includes original box, gig bag, and IEC power cable. Everything works, no issues. Keys are in perfect condition and all straight / no cracks etc. Screen is bright and pixels are dark (contrast is adjustable) with no fade or scratches. Never stored in direct sunlight. All the lights work and outputs have been tested. Knobs are all in great shape, and as far as I know they're real silicone, not the "soft touch" plastic stuff that gets tacky after a few years. It's got maybe 100 hours of playtime on it, heavily weighted toward the first few years of ownership.

Here's a review that dives into the features:

I'd rather not ship this, so trying local pickup first. I'm in San Jose and can meet up around the Bay Area within about 30 minutes of driving, or come test it out for a few minutes in my garage if you need to.
