GEWA mpc adapter French horn to trumpet

I've been experimenting with all sorts of things the past few months and one of the things I tried was a French horn mouthpiece on my trumpet (got a bunch of them laying around anyway). Without the adapter, the sound was reasonable (very mellow, not trumpety so obviously not a 'main mouthpiece') but of course, the mouthpiece didn't fit properly. Given that they're quite cheap, I opted to try a GEWA mouthpiece adapter. Sadly, it dampened the sound so much that it went from 'promising' to 'dud'. The adapter is made from aluminum and I'm guessing that somehow doesn't transfer the resonance properly (I don't like aluminum mutes for the same reason).

Does anyone else have any experiences with mouthpiece adapters? Are there any that do work properly or are they really just pointless novelties?

I highly doubt it is the metal - it is more likely the interface area(s) being all out of whack. When you put the horn mpc in the tpt it probably had 0 gap etc... cheap adapters can be pretty awful too. I have had some that were unusable. I will try a horn mpc in tpt later on and see what happens.

Cheers!

I doubt it's the metal, also.

But more than that, a French Horn mouthpiece is designed to produce a certain result tor the Horn, and vice-versa for trumpet mouthpieces. Why would you want to compromise the tone and other results on a Horn by using a mouthpiece that's not designed for?

Certainly nothing wrong with messing around with mouthpieces, but hopefully you didn’t expect it to actually work well; they’re both brass instruments, but obviously quite different.

If I were tinkering with an adapter, I'd start by wrapping electrical tape over the portion of the shank that is nearest the end of the trpt mpc receiver - to obtain a snug fit at that location. And then determine if further action is warranted.

For a more permanent solution, I'd look at brass compression sleeves that are used with plumbing tubing. There might be sizes that could be modified to fit on 2 locations of the FH shank to give a no-wobble fit in the trpt receiver.
I installed a similar sleeve on the shank of an old T-bone sized mouthpiece so it fits securely in an old Euphonium receiver.

I frequently use a flugelhorn mouthpiece with my Bb or my D for a non-edged sound, especially in church contexts. Of course, I have to wrap tape around the shank for fit. Anyone know of a good adapter for this situation? (*and before you ask, yes, I have tried Curry TF cups and other similar options, but they don't yield the result I want)
