"Bass Trombone! It's like a musical bazooka!"

My school's bass trombone has been having abnormally out of tuned playing and it is really worrying. Eeek!  This bass in particular is a Benge 290.  Also note, I know the sound isn't great but I haven't played this horn since sophomore year and I'm currently a senior with a bass of my own.  Here are the videos in question:
https://youtu.be/-QY7M6DirFY
https://youtu.be/VEMEfJkjKBI

Any ideas? 

Edit: in the second video it actually did change the playability of the horn after re-watching the video.  Here it is:
Open: Eb
First valve: G
Second Valve: F
Both: Bb

The valve linkages are strung incorrectly.

Yup, your valves are already engaged. The valves may be 90 degrees off as they are hooked up, I'm not sure. I'm not sure how the linkage could be put on that way. Odd problem.

Are the F and Gb cores switched? The keying on the spindle may be 90 degrees different, so even with everything strung up correctly they won't work.

Interesting. On the video link it states that the horn just came back from the repair shop? If so that's tragic but it should be returned by the band director for a fix. But if that's true I wouldn't trust that repair shop to clean my mouthpiece.

Can you post a photo somewhere with a closeup of the linkages and stringing?

I know a French horn player who got used to playing primarily on the Bb side because his switch valve had been strung incorrectly when he was learning to play. As a young professional he was still playing the same way.

That's actually a super interesting story! I wonder if he still plays that way?

There are a few French Horn professionals who have converted traditional F/B flat horns to work this way. Most high horn players (1st & 3rd players) spend more time on the B flat side of the horn.

I've sent it to the repair shop and it actually isn't bad as it seems.  It turned out that it wasn't restrung correctly.  That's the downside of string linkage IMO although besides that, the 290 is a great playing horn compared to the condition it was in my sophomore year.  Very underrated bass IMHO and probably the only few independent basses I like... just my opinion.

As Rockymountain notes, pro's have been doing this for years... long enough that a number of horns are set up so you can easily string to "stand" in either pitch.  Makes life confusing for a novice who picks a horn "just like ...." then runs into fingerings that don't match the book  Eeek!

I asked a great French Horn player/ repair tech why so many horns are set up with F as the default key. He said, "Because players are still deluding themselves that they use the F side more than the Bb side."  :D

Never look at the conductor. You just encourage them.

Have you noticed, some folk never stick around to help tidy up after practice?

That's the downside of string linkage IMO ...
Really?

Would it not actually be the downside to using that repair tech?  My 14 year old daughter used to be able to re-string her valve correctly by herself.  For an alleged instrument repair person to foul it up is unforgivable and no fault of the valve design ...  IMO.

 Amazed Amazed Whoops, I read that wrong as " It turned out it wasn't strung incorrectly "

I also figured there couldn't have been any other possibility so when I saw that (and read it wrong) it really had me curious lol. Thanks for highlighting it, Bill.  Good!

Agreed. A properly strung linkage works great. This mishap is completely on Mr Fix it guy.

I just stared at a 290 for some time this last Saturday.  I have a REALLY hard time imagining how the tech mis-strung it.  Must have been a special, unique talent.  Wish we had a picture.  That would have been a classic.

Wonder if this is the same tech responsible for this horn "... is great playing compared to the condition it was in ... sophmore year..."?
