trumpet meet-up - new cup shapes

Picture
Check out our new 5MM Cup Shapes at "Trumpet Trials" where everyone is welcome to bring a horn and play duets, trios, etc. while checking out the latest gear at Harrelson. This is the ultimate trumpet hang that happens every other Thursday night from 5:30 to 8:30pm. Bring a great attitude and your curiosity as we get social with the Denver trumpet player's scene. Try our first 3d printed Cup options in high quality bio-safe materials printed on our high resolution DLP printer. These new experimental shapes offer extra compression that is not possible with modern day machining techniques.
