Why A Screwbell Trombone?
Great Versatility!
You will be amazed at the tone color change as you change out the flares. I did not just pick a spot to cut the flare that would make it fit into a slim case. I spent time figuring out where the cut should be so it would effect the tone and not the blow.
Will the screw ring add a lot of weight?
No....I have designed it in such a way that it is not even noticeable to the player as far as balance of the trombone. However the ring does have an effect on the response of the tone. It makes it very fast so that articulation is very clean and effortless. The ring also allows for faster dynamic response from soft to loud.
It is amazing!
