Well Joe, i haven't cut any horns but...

This horn has little market value and would accumulate more value being cut if it were a good F.

Then you could be the lead designer in the new Conn F tuba!

It does look to be pretty easy as a good bit of the upfront tubing is fairly cylindrical.

I am assuming you would build your own valveset for the horn, as under .700 bore four-valve sets are fairly tough to find. From looking at the horn's branches, bows, and bell, I would be pron to think it would have a bit more projection than the YFB-822.

Go ahead and take the chance, Joe!

Nah. .687 valvesets can be harvested from beat up King Sousies and 2341/1241 BBb tubas. .650ish ones could be torn from Olds 0-99, Reynolds TB-10, Conn 5j.


Go for it Bloke!

Hey Joe,

Or could it be converted to a "professional" quality Eb?. Something with 5 valves or 4 plus a tuning slide kicker.

I'm starting to look around for a new Eb with purchase plans in a year of so. My problem is I really love the sound of my little 1920 Holton (not the intonation though), but nobody makes anything similar anymore. They are all 4/4 or 5/4. I've tried the Bessons and the MW so far and while very nice, not the sound I'm looking for.

I hope to make it to TUSAB this Jan. to try all the Eb's I can lay my hands on.

Based on what I've played so far though, I'm thinking I may end up buying an old horn and having it modified to my tastes - IF I could find one with good scale. So I've been keeping an eye out for and old 3 valver that might fit the bill, and I find your comments on the 60's Conn Eb interesting.

Do you think this would be reasonable? Any other thoughts? Anybody?

I cut one to an F in the early 80's.

I couldn't find a four valve block so I took a three valve block from a sousaphone, scavenged a valve from another, then had a tech silver-solder them together.

I did not cut any of the big branches but was able to cut most of the tubing from the area of tuning slide. I even had to shorten the ferrules on the tuning slide and making a shorter leadpipe (which I got from Allied). The tuning slide pull was short. Too short for comfort.

It looked ugly but had a nice singing tone. The low register was the pits and intonation was not good. I ended up giving it to a student who wanted to learn F tuba.

That was my last attempt a cutting a horn.
