I'm new to saxophone but been playing music most of all of my life. I currently content with learning and developing my embouchure on my current mp but eventually I want to invest in a good metal mp. Have any of you guys ever heard of a Russo? My sax tech plays on one but I can't seem to find any information online about them. I'm also interested in learning about the Guardala mp...its suppose to be a wonderful mp for a King Super 20. Any experience that you can relate will be appreciated.
