About Us

Born from Adversity. Forged in Obsession. Powered by What If?

At the heart of TromboneLAB was an obsession — not just to make something different, but to make it revolutionary.

It started with one question — what if?

What if your slide could change everything?

What if it didn’t just change how you play — but who you are and what you can become?
What if it transformed your mindset? Your confidence? Your identity?
What if it was fearless? Bold? Unbreakable?
What if it didn’t just sound great — it gave you freedom?
What if it felt so right, so alive, that it made you fall in love with the trombone all over again?
What if tradition wasn’t the future — but a barrier?

Could modern materials do what brass never dared — and do it better?
Could I build a slide that transformed your playing… and your story?

These weren’t just questions.
They were a challenge. A spark. An obsession.

This was the start of a revolution.

And the beginning of everything that followed…

Visionary & Architect of the Revolution

Colter Weatherholtz is forging a new era in slide design—one bold choice at a time.

After a career-altering setback — a setback that could’ve been the end — the path forward went dark. But in the stillness, something shifted. I no longer wanted what I lost. I wanted something more. A new feel. A new voice. A new future.
I didn’t want recovery — I wanted a revolution.

But to get there, I needed equipment that could do more than follow the rules — it had to break them. 

What existed wasn’t enough. What I imagined didn’t exist. So I built it. 

That was the beginning of an obsession. One that still hasn’t let go.

Now you know my story. It’s time to write your own.

A revolution for the bold.

What started as a quest to reimagine the trombone slide became something more — a movement, a method, a mindset. A vision became a breakthrough. And that breakthrough became a brand.

Every slide I craft is a reflection of the person it’s built for — born from vision and refined through obsession.

This is personal. This is precision. This is TromboneLAB.

A revolution for the bold.
