Who the 3506HAL 6.5AL Trombone Mouthpiece is For

The Bach 3506HAL 6 1/2AL is a small shank trombone mouthpiece designed for players who want the familiar 6 1/2AL feel with a tonal profile that leans more Germanic in color and core. It keeps a standard rim and cup geometry for comfortable endurance and predictable articulation, while the larger bore and #420 backbore are intended to support a broader, more projecting sound concept.

This model is also a practical choice for euphonium players seeking a round, mellow tone with strong volume and carrying power, especially when a small shank receiver is required. It is well-suited to advancing students, serious amateurs, and working musicians who need a dependable mouthpiece for ensemble playing where clarity and projection matter.

Common Questions About The Bach 3506HAL

Is the Bach 3506HAL 6.5AL the same as a standard 6.5A?

While both share an identical 25.40mm cup diameter and a medium-deep cup, the "L" signifies specific interior modifications designed to back a darker, more traditional German sound structure.

Will this fit my trombone?

This is a small shank mouthpiece. It fits trombones with a small shank (small bore) receiver and will not fit large shank receivers without an adapter.

Can euphonium players use this mouthpiece?

Yes. Bach recommends this model for euphonium players who want a round, mellow tone with substantial volume and carrying power, provided the instrument uses a small shank receiver.

If pump doesn't seem to work
Size: For 85-300 HP, Size: For 85-300 HP
Hi....I apologize it took me a while to get back to you with my results. Here is what I discovered about the pump and will also apply to some of the other comments I read in the reviews with people not getting the pump to work: 1.) I removed the pump to check the proper direction of the impeller and it was correct as can be seen in the photo. 2.) I built a pump shaft attachement so that I could operate the pump with a power drill. 3.) I attached the water muff to the unit and tried to pump water.....it wouldn't do so. What I did see however was that even at high hose discharge and small leakage at the muff I could not fill the water cavity in the housing. 4.) I installed a strap around the muff and tightened it very tight and THEN at high hose pressure I was able to get the cavity to fill with water. 5.) At that point I activated the drill and was able to get the pump to actually pump water. I then removed the pump housing and removed the O-Ring that resides on top of the impeller, reassembled and it would not pump water. Since the O-Ring sits higher than the original does I wanted to make sure that it was necessary to have it in the pump. 6.) I reassembled the engine and kept the tight strap on the bottom and finally it pumped water into the engine. My conclusion that you can reply to other buyers if they have a problem: Do NOT underestimate 2 things....1.)the lack of ability of the pump to draw water up AND 2.)the fact that if the muff leaks it will NOT fill the cavity when common sense says it should. This was a 120hp Johnson. The engine bottom must be immersed fully or the muff must be very tight on the lower unit for the pump to function. Please feel free to post this if you wish.
