I purchased this at a shop in Aloha Tower during the 1996 Honolulu Marathon and have kept it in its case, hardly ever playing it. I believe it's the KSM-00 model. I recently learned that this manufacturer started around that time. It wasn't very well-known then, but it was still a solid-core, single-piece koa wood, and cost $350 at the time. I loosened the strings to prevent the frets from warping. I haven't played it, so I don't think there are any scratches, but there might be some minor scuffs from handling since it's been in personal storage. Please understand this before purchasing.
