"I love the way the carbon fiber feels! My first couple minutes playing on it and it feels dialed-in to a tee! I'm really diggin' it!"

“Finally, a carbon fiber slide that doesn’t get sticky after extended playing, and that looks and plays even better than brass! It has become the ultimate jazz horn for every style.”

"I LOOOOOVE IT! The action is so light and I can get my ideas out much more easily. Thank you Colter. Amazing work!"

“The slide is so smooth and light that sometimes I forget it’s there! It is indestructible and also looks great! I highly recommend Colter's work."

"Slotting is better than any other slide I've tried! Notes just lock in immediately, and the tone is like a laser beam! Really outstanding! I already love it, and no doubt, it will be my favorite go-to option!
