I have played Bill's rotary C trumpet with the slightly brighter bell in a variety of settings. The horn is very easy to play in intimate one on a part small ensemble settings as the rich warm sound blends well with other instruments. I do have to spend a few days getting used to the timing of the rotary valves, but I find it very manageable. I use my normal C trumpet mouthpiece--even so, the rotary seems easier to respond at very a very soft dynamic. In short, this horn instills confidence.
