of course its all based on preference, but I think they have a complete sound..when I think of what a HBCU band should sound like, its SU. All their sections complement each other, and there's no weak link.
Yall and TxSU can be so much better if yall get yall's trumpet numbers up. TxSU is straight low brass, but whoever arranges the Boom's songs does a good job of hiding their trumpets. Yall still sound good as hell tho dont get me wrong.
I do prefer JSU's darker sound over SU's light sound. I know Haymer tried to change that by replacing baritones with euphoniums and switching to all brass tubas over the fiberglass ones, but they still dont have that dark sound like yall.
The old Jukebox was like listening to a radio with the volume on 100,the treble all the way up and the bass on 1 thats how they got their sound to travel so far imo but now they have damn near 300 something every year so they can play around with the instrumentation to however the directors see fit
Yall do have a unique sound..i never thought about it being a jazz sound, you may be right. I can be blindfolded and pick out a JSU, SU, FAMU, BCU, Norfolk, TxSU, Howard, Talladega and Bama State clip based on sound and arrangement history/tendencies for each band
