I hav a YFH-6310Z flugelhorn (bobby shew model) and have been noticing quite a spread of flugelhorn receiver types among various horns. The mouthpiece that came with the horn has a much smaller shank than a curry flugel mouthpiece i bought, and the reciever size is smaller than a kanstul flugel receiver but larger than some besson flugel recievers i've seen. What are the standard receiver types for flugelhorn (or the most commonly used?). I want to know either what type of flugel mouthpiece shank to request on a new mouthpiece, or what type of reciever to get on a new flugelhorn. Can it be just as simple as getting another tuning slide or a sleeve from Bob Reeves? Thanks!
