I have mentioned these before as some may remember, they are from the U.S.A. and are a range of low brass tenor & bass trombone, euphonium & tuba mouthpieces with detatchable rims, cups & shanks. This gives a huge variety of options and if like me, you use different instruments, you get to use the same mouthpiece. The other alternative of course, is that you can match the cup & shank to a particular model. They are also available in a variety of finishes, silver, gold & lexon (plastic). The website is at www.dougelliottmouthpieces.com and the on line info can be printed as catalogue. There are also charts to compare different brands. Be patient once ordered as Doug is a busy trombonist, however, he will always take the time to advise you if you are in any doubt. It's about time these were made available in the U.K. shops.
