Does anyone know of another .508 bore horn that is heavier and plays with a little more power?

Some Bachs are like that... But I wouldn't characterize most of them that way. They're "darker," more colorful maybe, but my 16M isn't heavier playing than my rather light 3B/F.
I'm borrowing a 12 at the moment that is almost... too legit. Massive sound, plays larger and louder than some 36s I have played. I actually can't imagine playing it in a big band setting... or much of anything else, actually. They're out there! But I wouldn't bet on finding one, even looking for it.
That is the Vocabell. It has the nickname "Razorbell" because it has no bell rim.BigBadandBass wrote: ↑Wed Mar 17, 2021 3:08 pmThis is offtopic, but is that the same as a Vocabell?
This post reminded me. Why not try wrapping some of the self-adhesive (no glue) stretchy medical tape tightly around the throat of the bell? After a few wraps you can put some coins or metal pegs in and wrap around those as well. It will effectively give you a heavier bell that plays like a heavy bell, but for less than $10. And it's not permanent.Cmillar wrote: ↑Wed Mar 17, 2021 1:40 pm We can't forget that different mouthpieces bring out different characteristics of any horn too!
Like, some mouthpiece that only brings out low/mid overtone colors and has a real heavy blank that really holds your chops together when playing loud could make your small bore horn sound pretty 'heavy' compared to sticking a lightweight mouthpiece in it.
Remember the Denis Wick 'tone-booster'? It worked as advertised when used on a Wick mouthpiece. It could make a Wick 7C behave totally differently and turn your horn into a different animal.
I've got the Courtois ac402trr (508 bore) and it's on the light side, but a really, really fine horn.Trevorspaulding376 wrote: ↑Tue Mar 23, 2021 6:04 am Saw someone mention a courtois, I have the 602 and 430tlr
Not sure either is Heavy but man they are fine horns !! Don’t get the credit or wide known recognition of some of the other brands , I’d definitely try a 402, I love my 2
Powerful would be an understatement.
Hard agree. The Recording is the move here, IMO.hyperbolica wrote: ↑Thu Feb 01, 2024 7:15 am Something slightly off the beaten path would be the Olds Recording. That probably fits the spirit of what you're asking better, even if its not straight 508.
