Trumpet - Johan Nordfeldt
”About five years ago a colleague recommended me to try Warburton mouthpieces. The possibility of combining different tops and backbores provides a unique opportunity to find a combination that works for each individual musician. Those were the qualities that caught my interest.
I use a variation of the 4SV top with some minor changes. It's a very nice piece. It has a nice sound in the low and middle register, and when you figure it out, it really opens up the high register.
It is the genuine craftsmanship combined with very good service that makes Warburton the natural choice for me."
