My 1047F from Getzen has served me well for a little over a year and a half, and I'd like to say I know its quirks and its flaws. But I do wonder how its wrap on the F attachment affects airflow, tonality, stuffiness, things like that compared to other wrap styles.

Also, this is my first post on TromboneChat, so hello to all users who stumble upon this post!

Good day and welcome!

Everything has an effect. But it is extremely difficult to isolate. Sometimes the difference is very small, and it can be attributed to the wrap itself, the difference in mass placement and balance (and thus horn angle to your face, and if any, vibration and damping of the horn), etc.

The most obvious benefits of Alessi-type wrap is that the condensation in the valve wrap drains into the slide like open wrap, while the wrap does not stick out as far, which makes it less prone to damage.

One disadvantage of open wrap styles in general is that you need a little extra clearance behind your head compared to traditional closed wrap horns. I’ve had a couple of situations with my open-wrap horns where I had to maneuver myself or something else on stage to avoid hitting something or someone hitting the tuning crooks. That’s a small price to pay for a horn that is better balanced and doesn’t need to have a crook removed to get rid of excess water.

In a word, not much of anything. You won't really note any similarities between the 1047 and a T396 or a Shires Alessi, despite having the same wrap, if you played them side by side.

The main disadvantage with that style of open wrap is that you lose out on some pull. Not that you need that kind of pull very much, but it's fun if you are into experimental music.

That's the genius behind the Lindberg / Minick CL2000 type wrap, which gives you the most pull. Also the original Kissbone X-Wrap, which gave a kicker near the trigger for extra pull when you need it for the low C, etc.

This style wrap is, very good/open, and even. Any stuffiness, usually comes from misaligned rotors OR worn rotors.
Getzen/Edwards are very good rotors (Ya, same valve)

As to possible water retention, usually not a problem. After playing (probably too loud) set the horn vertical to the floor (seconds). Water will migrate to valve. As you bring the horn up to play, open the valve. Water goes immediately to slide section.
