Was discussing this with a section mate a few days ago. Does anyone switch a mouthpiece/lead pipe combo for different purposes?

Such as a Bach 11C & a tight lead pipe for lead, and a Bach 6.5A and a more open pipe for lower parts, combo work, and concert band. Or an Elliott with one rim, and different cups. On a .500 bore horn.

Ideally, you would use two horns for the different purposes, but if you only have one horn, could this be an option?

If I changed leadpipes like that I can guarantee more chipped notes. Probably would be too confusing on the face for me.

I do occasionally. On my horn, the 2 included leadpipes respond really differently. If I’m playing a more legit gig under a trumpet player, I’ve put in a more open leadpipe to help diffuse the sound. On the opposite end, playing an acoustic set with a guitar and sax, I put in the open pipe and used a smaller mouthpiece to get more pop with less effort. So yes, occasionally I’ll run into a situation where it’s easier to make a small change. 95% of the time? Same leadpipe and mouthpiece for everything commercial.
