This is a silent bass, the YAMAHA SLB200. It also comes with an extension frame (BEF2). I used it for arco playing to practice the contrabass. I bought it when I lived in an apartment without soundproofing and had trouble playing at home. I also own a wooden contrabass, but there's no sense of discomfort when switching between them. It has enough features to practice and improve. However, the center of gravity is physically different, so I wouldn't say they're exactly the same. Before buying it, I wondered if it could be used for arco, and it was somewhat of a gamble, but I think it works well for arco. (Of course, harmonics also come out properly.) By the way, it has Belcanto strings. They cost over 30,000 yen. They were put on several years ago. The SLB200 has undergone specification changes, and the fingerboard has been changed from ebony to another material, but this one is probably ebony to the untrained eye. Please refer to the photos and make your judgment. It has been used, so there is a feeling of use, but it hasn't been handled roughly, so there are no significant dents or the like. There is a slight peeling on the sponge of the stand. The function is not a problem. Everything in the photos, including the stand, is included. The packaging will be a soft case wrapped in bubble wrap, with a shipping label attached, and sent as fragile. It will be sent in two boxes, the stand and the bass. It will be sent via Yamato Transport from Kanagawa, with a maximum size of 200 and 140. If you have a desired price, please comment in the system or in the comments. If you have any questions regarding the condition, please let me know in the comments. If you want to change the conditions, such as packaging, please let me know in the comments before purchasing. I live in the southern part of Kanagawa Prefecture. I also accept in-person handoffs.
