Griego (Griego) Mouthpiece for Tenor Trombone with Large Bore Nuvo Series 4M Lightweight List Price: 36,850 yen This is a popular size in the Nuvo series, suitable for a wide range of playing styles, from solo and ensemble to orchestral. I purchased it to match my European-style trombone, but it also pairs well with instruments like Yamaha and is surprisingly versatile. The rounded rim shape and lightweight design contribute to its clear tone and high controllability. Despite being a lightweight model, it does not lack volume and provides solid projection. Recommended for those who want to play with fine nuances, those who use instruments with lighter (thinner) bells, and those who use the W company's Valkyrie model and feel it's slightly lacking. It has been used very little, so there are no noticeable major scratches, only minor scratches from normal use.
