Mine's worked great with an RPC 90R, 105B, Jody jazz DV, Vandoren Java and Jumbo Java, Runyon Bionix, Runyon XL, and Smooth Bore, Selmer C*, Morgan 3C, Morgan Excalibur, Selmer Super Session, Yanagisawa Metal, Beechler Diamond Inlay and Beechler Bellite...Never played a berg. (In other words it's a very friendly horn...) I use the 90R as it's the easiest one to play...sounds great...and loud. Whatever works!
