I love it, it plays so well and has great control throughout All ranges

I bought this as a bright option to the JodyJazz DV7 bass sax mouthpiece I normally use. To be fair I haven't had a great amount of time to get used to it on the Bass but on Baritone it works a treat. For the rock/pop musicals I sometimes play it'll be great and really cut through the rhythm section.
Another nice mouthpiece - 😊

The Syos for modern bass works great on my Thomann bass. It helps brighten a dark sound, even if it is a bit hard to tame.

I use a Spark bari piece on my Gary Sugal Series IV low A bari, and a Smoky (demo) on a (new) Thomann Jazz Bari (no low-A). Each one serves to moderate the sound of a particular insteument, so I can dial in the tone I like.

C’est un excellent bec (7*) sans aucuns problèmes pour sortir un son net et précis. Il convient aux saxophones basses modernes et est très flexible tout en offrant une puissance sonore vraiment élevée. Je recommande !

Bought a bass mouthpiece and couldn’t get a peep out of it. No-one’s fault as these things are personal. But…. Had to wait for delivery from France and then pay for postage return. I wouldn’t buy from them again unless it was in person.
