What would the different cup depths on the Hammond bass mouthpieces compare to? I can find info on the rim sizes, but not the cups themselves. I know some people have described the BL as shallow or bright, but that's really all. I'm currently using a Schilke 58 if that helps.

BL is still pretty deep on the 20 size. My 19BL got really shouty, the 20BL less so.

The BXL depth is silly deep, borderline useless.

I know Matt Walker has some customs in BLL, between the two.

I personally am not sure I dig the Hammonds- the throat is so big that it just doesn't really jive for me on any of my horns.

Even with that I honestly like playing it with the Markey 87 better. Probably should just sell it at this point, as I don't think I'm ever going to put it to any real use.

The Hammond 20BL feels shallower to the touch than a Stork 1.25, which is measured on Stork's website at 36.8mm. Like Aidan said its a very wide throat so it feels bigger than it probably is. I play tested both the BL and the BXL cups and found the BL better suited to punchier commercial settings and the BXL to a richer orchestral sound. Both cups utilize the same throat and I've recently moved away from the Hammond's because of how large the throat is, but I know some people love a more open feel.
