Conn 90G upright valve trombone

Postby Curmudgeon » Sun Aug 21, 2011 7:11 pm

The Conn 90G was mentioned in a thread a couple of days ago...

Here's a couple of shots of a really nice Conn 90G upright valve trombone. The bell sections (they used the entire section) were from the Conn 8H (large bore tenor trombone, most commonly seen as the 88H with an F attachment) and the valve section is from the Conn front action American baritones that were made for so many years. The 90G was on made for @ a year (1969-1970).

They were made for a specific college marching band program (school's name escapes me right now).

The 90G is the best playing valve trombone I've ever used as it's a whole notch or two bigger than the pea shooters most people know (and dislike).

They were all nickel plated. The one below is not currently for sale.

I see the lock on the bell. Does the valve section detach?

No, that nut was soldered in place.

I believe I could build one of those, maybe, out of an old beat-up Conn baritone and a beat-up Blessing B-88. (I really wouldn't want to trash an 88H to build one.)

I know you could. Bloke-O-Phones... These are really cool little horns.

Pure formalism, but Conn used G to designate their valve trombones. This is the 90G:

I think these were originally intended for Ohio-State-type band market.

Anyway, thanks for the fine photos!

Sometime a decade ago I saw photos of a 90G, where the nickel plating over the nut joining the bell section and the body was so smooth that it looked like the joint was not intended to be taken apart.

Thanks for that, Klaus. I knew it was a 90G. It's tagged a 90G. Why I called it a "90H" is purely a brain-hiccup! Tired, I guess!

Yes, that joint is completely smoothed over. The knurling is still visible, but smooth and non-functional.

Thought you might like the pics, too...

One more unrelated bit...

On the page Klaus posted, there is listed the 48H. I have one from the late 1950's. What a great tenor trombone! Highly recommended, especially the earlier years when they had a nickel plated copper bell.

For the rare trombone freak on TN here the other Conn cat page from around 1968:

At leat on my monitor not all of the scan is visible within the TN page. Right click and open in a separate window, then you can see it all.
