This is a Yamaha BB235. I impulsively bought it at Shimamura Music, but bass isn't really for me, so I'm going to sell it. I've only used it twice, and I've loosened the strings when not in use, so I think the neck is fine and doesn't have any warping. - Brand: Yamaha - Model: BB Series - Color: Natural - Headstock Shape: Straight Head - Pickups: Single Coil - Number of Frets: 21 - Body Material: Alder - Neck Material: Maple Thank you for looking.
