Volare tuba mouthpiece, BT-01F Selling due to a change of instrument. Offered at a relatively low price, so don't miss out! Used only a few times after purchase. There are minor scratches on the shank, etc., but the rim is without scratches, and I believe it's in good condition overall (personal opinion). The original box will also be included. Due to packaging considerations, the original box will be folded and included. Please check the photos for details. 【Product Description】 * BT-01F The BT-01F has reached a level of completion as an F tuba mouthpiece. Rim inner diameter: 32.03mm Throat diameter: 7.50mm Cup: Slightly shallow V-cup The shank is American shank. * Volare does not manufacture Euro shanks. * The concept behind the design is to intentionally create unevenness inside the cup to improve the sound, so hairline scratches (marks from machining) may be noticeable inside the cup.
