The Marcinkiewicz mouthpiece is characterized by its light and airy feel, while still allowing for maximum control across the entire range without the high notes becoming thin. It is also known for having very little individual variation compared to Bach, due to its precise design and drilling technology. Equivalent to Bach 12c Although a marcinkiewicz 12c exists, the 12c is shallower than the Bach 12c, and the 12 (without the c) is closer. According to the catalog specifications, it is similar to the signature models ET1.7 and ET3, both of which are highly regarded within Marcinkiewicz. My personal impression is that because it is lighter than Bach, the breath flows in smoothly, and it gives the impression of excellent controllability. Currently, the lead time for new Marcinkiewicz mouthpieces from order to delivery is uncertain, and it is said to take about six months to a year. The number of used ones available is also not large, so please take this opportunity. 　Scratches on the shank (photo)
