This question if following on from my thread "Whats the best trumpet?" So i want to know what makes a trumpet better than another? What makes a Bach trumpet better than the chinease trumpet i got or another cheaper trumpet? I mean a trumpet it designed all the same (i think) 3 valves, same hole structure in the valve where the wind goes through, samed structure etc. This also goes with a mouthpiece. Whats the comparission?
