Description
Carbon fiber leadpipes offer great response and openness. We build these with a very thin wall to allow for very fast response and great articulation. We offer two sizes for each bore size. Short and long versions. The short version has a wide open sound with very little resistance. The longer version is more focused with slightly more resistance. The threaded “nut” is 3D printed carbon fiber and is very durable. We offer these in course (Shires) or fine (Edwards) threads. We also offer press fit for .500 and .508 bore horns.



Gregory Waits –
I bought two of Dave’s carbon fiber leadpipes for my Conn 6H after having the slide rebuilt.
My first impression of the long version is that slotting improved in the upper register. Another thing I like is how much more resonance it brings out of my horn. My sound is a bit brighter, but not to the point of being strident or shrill.
I’ll be trying the shorter Butler pipe soon.
Grrat stuff from Butler Trombones! I highly recommend these leadpipes.
