The Bach 351 trumpet mouthpiece collection is the archetype for most modern mouthpiece designs. The vast range of sizes available allows any player to choose a Bach mouthpiece and improve their comfort, efficiency and sound. The sizing system illustrated here is used by many other brands and has become a standard for comparison.

Most of these descriptions are culled from the Vincent Bach Mouthpiece Manual, which is worth a look. The manual is a treasure trove of information. The last sentence in each, comparing the size to the adjacent mouthpiece, is based on viewing the Kanstul Mouthpiece Comparator.

The Bach mouthpieces below and those in the drop down menu are the models we stock. There are a few other sizes readily available. If you wish for a more obscure size of Bach mouthpiece, please call or email. Most sizes are available within 1-2 weeks. We also stock a selection of Bach cornet and flugelhorn mouthpieces.

Looks Fantastic, but you HAVE to follow the setup directions!
Color: Rustic Brown and Black
BLUF: I bought this for my office to display photos, awards, and such and I am very happy with the purchase. Background: I moved into a new house and needed to organize my office. Like most people, I have a bunch of nicknacks, paperweights, and small gifts given over time. And like most people, I had no efficient nor aesthetically pleasing way to display all of the items. I didn't want a big solid bookcase, but more of a display case to show them all off. I bought this and am very happy with the results. I would suggest it to anyone, however it is not perfect. PROS: Enough shelves with enough space to hold all of the small items that I had. It is solid if installed correctly. Additionally, it is smaller and fits flush against the wall, giving the room organization and improving it, while not overburdening it and making the room feel crowded. CONS: The main issue is that the single bar going up through all of the shelves makes it very flimsy if you don't secure it to the wall. YOU MUST SECURE IT TO THE WALL PROPERLY!!! I cannot express that more. Once you do, it becomes a solid piece, but it will not function properly if you do not secure it at all 4 attachment points. Overall: I would buy this again!
