Bass Trombones with Mismatched Valves

Does anyone have any pictures or examples of bass trombones with different types of first and second valves. I’m sure they must exist, but I have yet to see more than one example.

I’ve seen maybe 2 or 3 in the last few years. I seem to recall a Bach 50T (single) that had a Yamaha rotor added as a dependent. I don’t remember off hand what the others were so it’s more rare than one might expect with as many tinkerers as there are

Handful of single Thayers with a drop in rotor. A couple of rotor horns with a dependent Thayer out there, too. Plenty of examples of modified singles with a slightly different rotor as the second valve, either in-line or dependent. (Including the semi-famous example of an early G. Steucil (sp?) independent bass trombone).
A few of the examples have been done this way for playing reasons… I think 99% are probably done like this due to part availability.
Cheers,
Andy

The most fun one was that 50G with Olsen rotor, then dependent Olsen axial.

Any chance you’ve got a picture of that one or know where I could find any info on it?

Hmm, I thought I might have a picture saved but I can't find any.

I have a guy who brings his bass trombone into the shop about once a year for a cleaning and tune up. It it a hodge-podge horn of assorted parts, but the primary aspects of the horn are:
*Olds bass trombone slide and bell
*1st valve (in F) is also an Olds, although I not sure if it is the original valve for that horn. Approximate bore is in the .560 range.
*2nd valve (independent in G-flat) is from a Benge 290 and it is a bore of about .592 inch.
There is huge difference between the feel of the two valves. Obviously, the G-flat side is much more free-blowing. Thus, the owner favors the G-flat side for everything. I think he only engages the F-valve for low D-flat, C and B.
Sorry, I don’t have any photos.

I had an old Bach that had been a tech’s experimental horn. The valve was modified so the exit and entrance tubing was straightened out (like the old Thein “Star” Valve). It was too open. I needed a second valve pronto, and my old tech found an old Conn 110H valve. We simply grafted it onto the horn. I played the horn that way for too many years.

This was a project that I had Scott Sweeney build. His work is fabulous - axial valves hit my jaw and neck to the extreme so I only use dependent rotary valves. He came up with this design after our talks.

I get it about the parts hitting the jaw and neck in uncomfortable ways. This bass does look well crafted.[/quote]

I’ve owned this horn for about 8 years now and I love it! There’s more info from the original owner and the build in this thread: <LINK_TEXT text="viewtopic.php?p=12287#p12287">https://trombonechat.com/viewtopic.php?p=12287#p12287</LINK_TEXT>
