I'm a trombone player, and I've dabbled in the valved instruments, but never really settled on anything. I've got a tuba, but I'm not sure I'm going anywhere with that. I've had a Wessex Dolce, but sold that for some reason. I've owned those marching valve trombone things, and liked them but I've got a pinched nerve, and couldn't hold it out in front of me. I think I need something that I hold closer to my body, a little more ergonomically friendly, but still useful if for nothing else than to just practice valves.
I'm not sure I have an ideal, or a real goal in this search, but I'd like to get something probably used, something that could stand in for a bass trombone in a pinch. That would seem to mean 5 valves, which I don't think exists. Is there such a thing as an F baritone? Is that just really called a tuba?
Also, is there any big difference between a baritone and a euphonium that might interest a trombone player?
King 2280 or real 3+1 compensator?
