Hello all. I have a Yamaha 691 that I purchased years ago with an aftermarket leadpipe that does not even thread into the trombone. I really enjoy the sound and response of this horn, but I’ve always struggled getting it to intonate across the range in a way that is consistent with the other horns I play.

Is anyone selling a YSL-691 leadpipe or three?

Does anyone know where I might be able to purchase a compatible replacement?
