Unlike a trombone where the leadpipe is contained or hidden by the outer slide, on a horn what you see from the mouthpiece to the change valve is the leadpipe. It is easy to see any damage, dents, dings, and other things like red rot [dezincification]. any holes that happen will be pretty visible if you keep and eye on it. and yes the typical metal problems occurr just as much as any other instrument. paxmaha

My husband owns several old trombones (1940 and older) that have had to have the lead pipe replaced. When the pipes were removed, at best they looked like swiss cheese, at worse they came out in pieces. Can the same thing happen to the inside of a horn lead pipe (brass is brass after all) and how would you tell if your old trusty horn needs a new lead pipe? A trombone slide you can look through, but even then you can't tell if that pipe will come out in one piece or not. Kathy Anaheim, CA P.S. Do not watch a slide guru work on a trombone slide if you are the least bit faint of heart. Scary. _______________________________________________ post: horn@music.memphis.edu unsubscribe or set options at http://music2.memphis.edu/mailman/options/horn/paxmaha%40yahoo.com _______________________________________________ post: horn@music.memphis.edu unsubscribe or set options at http://music2.memphis.edu/mailman/options/horn/archive%40jab.org
