Hello,

Could anyone help me to recognize this?

I am looking for a gold ring weighted like a megatone. But this is not looking as a Bach.

I would like to know if I have alternatives

Looks like a Denis Wick with the Tone booster on and alot of hair

Agree with the tone booster. Not sure if it would be limited to Dennis Wick. Could be any piece with a gold rim. The booster also looks like a wick but there are a lot of alternatives. The angle is kind of weird, and the shank looks like it might be raw brass which means it could be an Elliott with a gold rim. I would actually lean towards that guess myself but it's pure speculation. One of the reasons I might suspect that though is this looks kind of like a king based on the paddle and cork barrel (6b?) but again, angle is really hard to tell.

What do you mean "gold ring" and "weighted like a megatone"? You mean gold rim? You can get a megatone gold plated, or just have the rim gold plated. Mouthpiece express offers both of those options. Note that the megatone is not merely heavier than a "regular" weight Bach, but also typically they have a larger throat and backbore too.

Edit for example, they have Bach 1.5G in stock:

You can select "Gold plate (24k) Rim & Cup Only (+$59.99)" and you'd end up with this:

nice, yes, I meant gold rim!

I would also try the tone booster anyway, thanks for your support!

Actually, assuming bass trombone, that looks exactly like one of my XB cups, with a gold rim, and brass shank. The cup outside is big like that and the rim is thin. If I knew who it is I might be able to tell you.

You can see the hex shape on the shank.
