I knew Marienthal couldn't have been playing on a stock beechler!NatureColor said:I'm assuming it's for alto. I'd say send it to a refacer and tell him what u want from the reface. I got mine from John Reilly in the Orange county, CA area. My jazz teacher Eric Marienthal and other pros from the LA area get theirs done there, by the way, Marienthal plays a refaced customized beechler from John. Overall it'll cost about i'd say 50 for reface and 60 for customization? so 100 dollars you won't need another mouthpiece!
