“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!

Welcome To The Future.

Nothing else compares. That’s the point.

Welcome to the lab — where tradition ends and something unexpected begins.

These slides don’t just feel different — they are different.

Built from a fusion of bold elements and an obsession with feel, precision, and fearless design, each slide dares to be different — in ways you’ll only understand once you play it.

You may not know exactly why it feels better. You’ll just know you’re never going back!
