It's discontinued now. Replaced by the S-1. The S-O got mixed reviews, but I have one and like it a lot. I replaced the tuners with closed gear Grovers. Also added a passive pickup, and switched it to low G tuning. I use it as my travel uke. The S-1 also gets underwhelming reviews, but I've tried a couple and think that they are great, especially with the extended fretboard.
