I don't know that I've read anywhere that discusses the issue of the material used in Schilke leadpipes. Lots of 'em discuss bell material but that's about it.
I was cleaning the B1 this afternoon. While wiping down and drying the horn the sun caught it and I thought "that leadpipe extension is a different color from the other ones". Held up the different slides next to it: Yup, no question. The leadpipe on the B1 is definitely "red brass" while the rest is yellow brass.

My B5 had a red brass leadpipe. It is my understanding this material is used to prevent red rot.

Right you are, B5toL. The higher concentration of copper means a lower concentration of zinc means less sensitivity to "de-zincification" which is red rot. But I've never seen it written anywhere that Schilke use red brass in their leadpipes. I would guess that they use it in all their models, but that's purely speculation. Anyone got any observances?

I would suppose that any discussion of materials regarding Schilke trumpets concentrates on areas where it makes a significant sonic impact, rather than strength or longevity.
Would a leadpipe made of all red brass versus a mixture versus only yellow brass make a difference in sound? Probably not. My Holton uses nickel instead of brass for everything except the valve casing and bell. The soul of the sound comes from the bell, in my amateur opinion.

Mike is right on. What I have learned from various sources including books and horn builders is:
The bell is the most important part of the trumpet. The sound/standing wave is set up at various nodal points of the bell. So using red brass in the leadpipe will not have much affect on the sound of that horn, but may help the longevity. There are some other opinions out there about leadpipe/materials, but when I have tried various leadpipes with modular horns (Edwards/Getzen), I didn't find the leadpipe changes made a huge change in the sound. They did affect the blow characteristics (resistance) for me, but not much sound wise, very slight and not noticable to others in the room unless I went to too big of a leadpipe and had to struggle a bit more up top.

Hi LIP,
Can't you make a horn a little more free blowing by opening up the venturi on the leadpipe (without changing the leadpipe)? For a lot less money, that might work...right?
Thanks.

Roy Lawler opened the venturi on my B5 from a.341 to a .344. It opened the low end of the horn and the high G slotted better. Before I ordered my Lawler, the rep at Schilke said they would open a B1 venturi for me if I gave them the specs. But I decided on the Lawler because of it's sound, blow and Roy is nearby.  |
