This is a tenor ukulele HF-36 made by Kamaka, a long-established brand representing Hawaii. It's a white label model, so the body, neck, fingerboard, and even the bridge are made of Hawaiian koa, making it a very luxurious model. Both the body and neck are in quite good condition. The wood grain is very beautiful, and it's an individual with a wood grain close to the deluxe model. It has been customized into a 5-string ukulele so it can be used as a solo ukulele. The nut and bridge have been modified, and the 4th course is strung with double strings of low G and high G. By restringing, you can also make it a 6-string ukulele (with the 1st and 3rd courses as double strings), or a 6-string ukulele with the 1st and 4th courses as double strings. Also, by removing either the low G or high G string of the 4th course, you can enjoy it as a 4-string ukulele. Double-string ukuleles have the charm of a unique chorus-like sound, and you can get the overlapping sound as if you were playing multiple ukuleles. Also, because the head is longer than a regular 4-string, it resonates well. I only enjoy the sound at home and have never taken it outside. It was my favorite ukulele, so although it's hardly noticeable at a glance, there are some playing scratches if you look closely. I think it's in pretty good condition for a ukulele of this age. The bright, crisp sound has a different sharpness than other ukuleles. I own about a dozen Kamakas, including the deluxe type HF-3 D2I, the current HF36D, white labels, and gold labels, and each one has a distinctive refreshing sound, and I love the over 100-year history and the familiar "ukulele-like tone." It's hard to see, but when held up to the light, there are beautiful "weather checks" on the painted surface. The KAMAKA HF-36 is in good condition for its age, but it is still a used item, so there are some scratches that do not interfere with playing. Please refrain from bidding if you are looking for new-like quality. How about it?
