Selected from five at a shop in Kinshicho in December 2025. I'm selling this because I settled on another BD6. Only tried it out. There are no scratches that would hinder playing. According to the manufacturer's figures, it seems to be slightly more open than the B40, but the blowing feel is like the BD series, with the air going through smoothly. There is no pitch instability, which is common with the BD series. Compared to the B40: The low and mid ranges are very similar, but there's no feeling like it might "gasp" when trying to play a strong low note. The high range also allows the air to flow well, so there's no feeling of it getting stuffy. I've been using the B40 for a long time, but due to repeated minor changes, it's become difficult to find a usable one among the recent B40s... I reluctantly tried the BD4 and 5, but they didn't quite fit. If you're looking for a B40 alternative, if you want to fix the quirks of the B40 mentioned above, or if you've had a similar experience to me, please give it a try!
