This is the signature mouthpiece of Roger Ingram, a high-note hitter who has been a lead player in many famous orchestras and big bands, including Maynard Ferguson, Woody Herman, and Wynton Marsalis (Jazz at Lincoln Center Orchestra), and is also highly popular in Japan. It is produced under Roger Ingram's private brand, One Too Tree Music Products, with the full supervision of Mr. Ingram himself. The design is based on a mouthpiece that Mr. Ingram once loved, custom-made for Maynard Ferguson in the 1950s by Dominic Calicchio, and has been designed and improved upon. The MF1, later produced by Giardinelli, is based on this Calicchio. The inner rim diameter is about the size of a Bach 12. The rim is flat and slightly thick. The inner edge of the rim is slightly sloped. It has more edge than the Jet Tone MF model. The cup is a shallow V-cup shape, about the size of a Bach F. Like the Monette, Eric Miyashiro, and Bobby Shew models, the straight part of the throat is quite long, making high notes particularly stable. The backbore is about the size of a Warburton 3. Recommended for lead players who need high notes. It has a resistance and is designed to make high notes above high Bb easier to hit. It has a good response and a very brilliant and fast-paced sound. It is designed for easy high-note control and lip control. Recommended for big bands and pops in wind orchestras that require high notes. Also recommended for those aiming to be super high-note hitters.
