If only my Martin III had Selmer keyworkAny discussion of complex, luscious tone in an affordable horn with excellent build quality has to include the Martin Committee III, especially the early ones. As far as how close it is to an SBA tone would be for you only to decide.
Here’s one: https://www.jlwoodwindrepair.com/shop/name/jl-custom-unlacquered-rose-brass-tenor-saxophoneTry out the JL Woodwinds tenor. I have played several of them alongside my SBA. They sound every bit as good, and if anything, they project better. John Leadbetter has designed them with the SBA bore geometry, but with Mark VI-style keywork. I have a thread in the Miscellaneous Manufacturers section that provides both pictures and more information.
In my view, Yes, there are some saxes which will get you close, but nothing which replicates.I love the dark special tone that many people can get on a good SBA but of course the prices have gone nuts. Any opinions about excellent quality horns (vintage or modern) which can come close (and of course are more affordable)?
