This alto is incredibly free blowing and resonant, which I believe is due to the gold plated metal resonators. I found the overall tone to be clean, spread, and even throughout the horn. Mauriat will add to some of their current models to enhance these models even more. The Greg Osby Model, being the 76 3rd edition model is the first to carry the design improvements which I hope P. This alto incorporates the System-76 body design, which from my recollection reminded me more of the vintage saxophones when compared to the 66 model which has the rolled tone holes.
In addition, there are double arms on the low B and C key as well as an extended thumb rest which I have rarely seen come on an alto saxophone unless it was a special add-on. The body to bow brace surprised me because it was 4 pointed, and I have only seen this design on the Theo Wanne Mantra tenor saxophone. This model comes equipped with blue steel springs and headed bullet point pivot screws.
The body material on this model uses yellow brass and the pads are Pisoni professional pads with gold plated metal resonators. In addition, the Greg Osby Signature alto had abalone key touches instead of white or black mother of pearl. The design on the bell was a dragon, which reminded me of the Selmer Reference 54 Dragon edition but a different dragon design. The engraving on the Greg Osby Signature model was on the body, bow, bell, and even the low C, C#, B and Bb keys. The detailed engraving on this model reminded me of a Yanagisawa 9937 which features extensive engraving on most of horn. The silver bell and bow, cognac lacquered body, and nickel silver neck made the horn really stand out compared to a traditional gold, black, or silver finish. At first glance, the Greg Osby Signature alto reminded me immediately of a King Super 20.
