Hybrid King jazz/salsa horn. 2B 1950s bell section with carbon fiber bell flare by David Butler. 3B mint slide with carbon fiber outers also by David Butler. I played 3B and 3B-F bells with the modified slide, then switched to the 2B bell for a punchier sound. There is also a vintage King counter weight on the bell section. The horn balances perfectly with it for me, but a younger/bigger/stronger player might not need it. If you have not already been blown away by the feather weight, speed, and ergonomics of Butler's equipment this horn will truly surprise you. ONLY selling because I have recently switched to the Butler .508 JJ all carbon fiber model and love it even more. $2500 shipped/insured in CONUS with new Protec case. Email me for more pictures or details. (Yes I will consider separate offers for bell and slide sections BUT please note that the 3B slide section has a 2B receiver).
