I have a Reynolds Emperor 'C' trumpet - it has always been hard work to play. Somehow I had never noticed - (don't ask ) - that it has one valve which is different. 1st and 3rd have 'internal' spring, the second has an external one. If this is a replacement maybe this is why it is so difficult to play. Any thoughts and suggestions would be welcome. Thanks. For instance - should I get rid and find something consistent in manufacture? Should I look for a Reynolds valve?
