Bob Reeves patented his sleeve system in 1974. This system allows the trumpet player to optimize mouthpiece gap for sound, pitch, and play-ability or to use the same mouthpiece in different horns that require a different gap. Once a mouthpiece has been converted for the sleeve system, different sleeves can be used in order to dial in the correct gap. Reeves Sleeves vary in diameter in small, but significant, increments thus increasing or decreasing the gap.
They are available in quarter sizes from #1 through #7 (largest gap is #1, smallest is #7). The change in gap from one sleeve size to the next is .0625" (1/16 inch). Sleeves are available in half sizes allowing for gap adjustments of .0313 (1/32 inch) and quarter sizes allowing gap adjustments of .0151 (1/64 inch).
