Good question and the answer is I don't know but would like to find out. I would like to try both the S42 and the B6 in different playing situations. I don't think anyone would let me borrow theirs to try for a month or so. If anyone does, I'll take good care of it.
I am looking for a good big band and rock band horn. However, I still need to play church solos. I like the bright side of Schilkes so maybe the S42 would be too dark. I don't know so I would like to try one for awhile to find out. The B6 might be great for solos, the S42 might be better for lead, etc. I might find the X3 does everything I want it to better than anything else. Then again I might find the B6 or S42 does everything better. Then again I might find one horn better for a certain style than the other. I am just curious more than anything. If I would pick one horn or two then I would like to try the same in a tunable bell, then the same in a tunable beryllium bell. Again just some experiments.
