Jo-Ral Grime Gutters for Sousaphone
Posted: Thu Aug 10, 2017 12:26 pm
Does anyone out there have experience with the grime gutters from Jo-Ral for their sousaphone. I can find them for euphoniums but I don't see any for sousaphones or tubas. Does the euphonium one fit a sousaphone valve casing? Any advice?
