On a regular basis, we receive a call or email at the shop that takes on the same basic form:
“Hi, I play on a ABC mouthpiece on a XYZ model trumpet. What sleeve would give me the best gap.”Usually, our customers are shocked when our answer is a resounding, “I don’t know!” After all, Bob Reeves invented and patented the adjustable gap receiver and sleeve system 40 years ago. How the heck couldn’t we know? The answer is simple – we only know two of the three variables needed to determine the best gap and really, we don’t know any of the three variables unless we have your mouthpiece and trumpet here in the shop for analysis.
