Maybe . . . maybe not. I'm not convinced that different types of resos provide different sounds. The discussion about resos vs. tone is much like finish vs. tone. It can't be proven (or disproven, I suppose).
Most saxophones have a natural variance, even among similar brands and models. To prove that a certain resonator does a certain thing, one would need to test MANY similar saxophones, record the results, dis-assemble, re-pad, re-test, etc., etc. The re-pad process alone ruins any objective assessment.
To compare just two horns of the same model is NOT an objective test of the premise, in my view. That one SBA sounds dark and another SBA sounds bright is way too subjective (few can even agree as to what is dark and what is bright) and even if so, no one can say why that is so, just that one sounds different from the other.
I'd be inclined to re-pad using the products that were originally used by the factory when the horn was first assembled, if they are still available. DAVE
