This model is a precision crafted & CAD engineered copy of a Dave Guardala MBII from the 1980s, around the time he was making pieces for Michael Brecker, Branford Marsalis & Tom Scott. This model is CNC milled from solid bell brass and .925 Sterling silver plated. It has plenty of power, and core tone due to the responsive baffle and large chamber. The mouthpiece blows very free with a huge sound making it ideal for Jazz, Funk, Latin, R&B etc. Each piece is carefully checked and adjusted by a skilled technician.
