No, but that's the only time I needed them. I had a PA80 some years ago, and briefly had Pa800 but didn't keep either of them long enough for them to break down. As a matter of fact, I haven't had this one long enough either.
As I said elsewhere, I was extremely vocal about how much I like the PA3X, and still do. I will also let people know the negatives, and for me that is service.
Everyone tells me they have had nothing but good service from Korg, so I'll shut up about it and move on. But I know how they ignored me and won't forget it soon.
