I play on a Bach 5G with Yamaha Ysl-356g. This mouthpiece works on small shank trombone ? For me , personally , this piece on my horn make a round,velvet sound and articulation is very clean, but at the same time my sound is like closed,cased,it seems strange, but so is,exist negative and positive sides with . I feel that air does not enter on horn , with this mouthpiece. Require very much effort . Resistance is very bad with 5g , and high register is big problem , maybe the low register is even better than yamaha japan 48 (my standard mouthpiece , good for all) .
Others opinions ? Is bad combination ( small shank + 5g ) or this mouthpiece not fit for me ?
