Thank you for the correction.

All modern trumpets and cornets have the springs at the top.
Some vintage models may have them at the bottom.
All modern flugelhorn (I think) have them at the bottom.

I much prefer the top springs, I hate the bottom ones in ly flugelhorn (alignement and stuff).
However, the bottom springs work ...

I'm in the same boat as you: 30 years playing trumpet, started trombones (bass then tenor) a few years ago and tuba 2 months ago.

I've been advised a Wick 3L for my Eb tuba, and so far I'm quite happy with it and am progressing quite fast.

I have a Jupiter JFH846 (predecessor of the JFH1100). My main instrument is trumpet and that flugelhorn perfectly fits my doubler's need (classical, big band, jazz). It works well (the valves require frequent wiping/lubrication) and it's very middle-of-the-road in terms of sound (not the darkest ...

They definitely fit in the "gig bag" category ...

Maybe you can find some answer here

Thank you for all the answers.

For a first mouthpiece I'll go for a cheap option, already spent too much on trumpet (also on trombone, but less) mouthpieces safari

I ordered a DW 3L and I'll give it a try.

Ok, so far the choice seem to be either a Denis Wick 3L or a JK Exclusive 6.
For those who know the JK, how would you describe the difference between the standard and the classic?
And should I aim for a 6B or 6C?

Hello,

After recently acquiring an Eb tuba, I'm searching for a mouthpiece to pair with it.
