Price reduced! Alliance, David Charles model DC4! For those who find the 5G a bit lacking, or who prefer a lighter instrument! DC4 Inner rim diameter: 25.75mm Deep cup Throat: 7.4mm Remarks: Shank - large shank, rim 6.73mm, comes with a black leatherette case and box While there are individual differences in instruments, when playing with a mouthpiece equivalent to a 5G, the intonation tends to be a bit sharp from the high E♭. However, with this depth, it fits just right. For those seeking a thick, deep, and bold tone, this is for you! The DC3 is also popular, but it might be difficult to control unless you have a lot of power. I think the DC4 is a mouthpiece designed for Japanese players. Price is negotiable, so please contact me if you're interested!
