Marcinkiewicz Trumpet Mouthpiece Comes with box, in excellent condition. The following is quoted from Net-Brass ↓ -------------------------------------------------- This is a Marcinkiewicz mouthpiece, popular among professional musicians in studios and big bands. It has the same design as the Charlie Davis model that was previously produced. The inner diameter size is about the same as a Bach 5C. The rim is semi-flat and the thickness is normal. The rim shape slopes gently towards the outer edge of the rim. The upper part of the cup is U-shaped, and the lower part of the cup is a V-cup shape, making it a UV cup. The cup is about the same as a Bach E. The throat is slightly narrower than #28 (3.57mm). The straight part is slightly longer. The backbore is about halfway between a Warburton 7 and 8. Among Marcinkiewicz mouthpieces, it has a core sound with a strong, dense sound. It is slightly bright and has good response, with a thick, uniform sound from low to high. The breath entry is smooth, and it feels like the vibrations within the cup are efficiently transmitted to the instrument. This mouthpiece is suitable for everyone from lead players to soloists. -------------------------------------------------- There are some minor scratches on the shank due to use, but there are no major scratches, dents, or plating wear that would interfere with playing. Please refrain from purchasing if you are concerned or are a perfectionist, as this is a used item.
