Soprano · Alto · Tenor · Bass · Contra Bass "Hey Jim, got the mouthpiece! Actually playing your charts on Brent Phillip's trombone festival in Colorado. I haven't been able to find an alto mouthpiece that feels right but this one feels great! I play a relatively big rim on tenor and I've always felt like I couldn't get my chops into the standard sized alto mouthpieces. Thanks for releasing these!" - Christian Dana Paarup Specifications: Model Rim Cup Depth Bore Soprano 3G Shallow Double Cup #5 A1 Alto Trombone 3G"C" Style.234" 1.7 Symphony Tenor Trombone 3G Medium Deep.281" B1 Bass Trombone 3G 1 1/2G Depth.284" C1 Contra Bass Trombone 27.25mm, 1.063" w/3G Contour Deep.281" Greg has been working with the phenomenal Jim Nova since spring of 2002.
