I have played my Hirsbrunner H2P for about 7 years and am satisfied with intonation for all but one note: Eb in the staff. It is significantly flat and I am thinking about a trigger that would allow me to push it in for this one note. Does anyone have experience with this issue?

I bought the instrument from Chris Quade and it looks like it was made in 1990.

You could try 2/3 - I almost always use 1/2 for E and 2/3 for Eb in the staff

I second the 2/3 suggestion. I have an HB1-P and found the same problem with second valve Eb. But 2/3 fixed it. I find more problems with the first valve than I do the others on mine. My first valve slide is very well aligned and that helps me fix all of those issues. The first year playing that horn was a bit of a brain teaser though. But with all of its short comings, I love my Hirsbrunner and wouldn’t trade it for anything as nothing else sounds quite so much like ‘me’.

My 2/3 combination is also very flat, but slightly easier to lip up.

As far as the first valve, I have a pull on the slide (and the 4th) which makes it easy to adjust to the A and Bb notes that are sharp. Very satisfied with this solution.

I had one of these for a while. Pitch on that tuba was actually pretty good. However, the best mod you could make is a trigger on the mouthpipe tuning slide as most out of tune pitches on the Hirsbrunner tubas are flat. Best of luck.

Hello Ben,
My previous F tuba was a Yamaha 621 and it had an interesting spring thing on the 1st valve slide. The basic idea is that the spring keeps it out where it needs to be, and you push in when you need to, and when you let go, the spring pushes it right back to the normal spot. I am not sure if I have pictures of that up close, but I'll check. A picture says a thousand words.
