Single Trigger Bass Trombones

Nobody here ever said that if it's working for you to discontinue, but that doesn't change the fact that calling it a bass would imply that every large-bore tenor trombone is also a bass.

There was a time that every trombone with an F-attachment was called a "bass". My Olds Ambassador A-20 was called a bass although it was smaller than most tenors.

100 years ago, most orchestral bass trombonists were using what we would consider a symphonic tenor with a single F-attachment as their main instrument.

Mine is a Courtois AC501R. I've been told by others on this forum that it is something of a rare beast: an open wrap single trigger bass. It looks to me like the single version of the Legend AC502R basses that were made by Courtois in the 90s in their Amboise factory in France.

I was fortunate to have been gifted at 50 B Corporation bass trombone. In certain situations it works great. It's the bell on the horn that really makes it wonderful. No, I won't chop it up with modern valves, it would ruin the integrity of the instrument.

I do try to use it as often as possible.

And here I go chopping up one today!

I’ve heard that horn a few times. It’s reeeaaally nice as it is.

The early Elkhart single?

The obvious clue is the under the thumb lever indicating that it could be a Mt. Vernon. The MV's main tuning slide tubes are longer. And, if the ferrules are beveled that's another clue.

MV 46b from Noah's was going to be my guess.

[Burgerbob]

It's a corp, but just barely. Also has no beauty rings on the slide ferrules.

What happens to those valve section castoffs? How would they fare on a 42B, replacing its undersized valve?

I've sold the valve section and leftover bits already, actually.

You wouldn't want to put any of those parts on a 42- the valve itself may be undersized on the 50 as well, but the ports and tubing are all bass sized at .593.
