I recently purchased a King Super 20 Bari sax, low Bb. I have been wanting to play a low b flat horn.as compared to the low A model I have. I have had the horn for two weeks and have played two rock band gigs with it, switching between tenor and bari. (tenor is also a super 20) I really like the sound. Usually I play a RPC 110 high baffle model mouthpiece, but also have an older (pickel barrel) mouthpiece that was opened up to 100. Though not as loud as the rpc or ponzol custom hard rubber mpc, it plays and sounds really nice. I has a vintage sound, sort of Mulligan like sound. Realy pretty. I know really pretty is not the sound you would describe for a rock band, but miked and amped the sound is there. I'm happy.
