Jen and I have begun shipping SpectraTone Red mouthpieces beginning with brass body variations, as those are finished.
However, we have noticed a large percentage of rim diameter errors with many people telling us they play small mouthpieces while ordering very large sizes. To be clear, you can save yourself a lot of time and energy by reading the mouthpiece comparison chart, and choosing the best size. If you are currently playing a small mouthpiece with success, then we recommend staying on a small size.
Remember, at Harrelson, we measure the actual Rim diameter where it meets the cup, as this is the actual diameter. Most other manufacturers measure the high point of the rim, which results in an inaccurate and inflated number not representative of the actual size due to inner radius variations. This means that any manufacturer using a high point value for a specific size is likely overstating the diameter by 40-50 thousandths of an inch. For example: our 680 rim is larger in diameter than any rim we have ever measured, so it is unlikely you need to order something larger than 640 unless you play on very large rims.
Another example: our 614 rim is the exact diameter of pretty much all common 3 diameter rims from Bach and related copies.
One more note: Almost all Jet Tone and lead-type mouthpieces measure .590 and smaller. It is highly unusual to find a mouthpiece measuring larger than .590 that is shallow and used for lead work. A .590 is the equivalent of a Bach 7.
Thanks for listening, and hopefully learning! We really want to ship you the correct rim size, but it is up to you to read the mouthpiece chart at https://www.whyharrelson.com/rim-sizes.html to do this correctly. We cannot exchange rims once they have shipped.
