About Us
Born from Adversity. Forged in Obsession. Powered by What If?
At the heart of TromboneLAB is an obsession — not just to build something different, but something 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?
What if it transformed your confidence, your identity, your future?
What if it was fearless? Bold? Unbreakable?
What if it didn’t just sound great — it set you free?
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?
These weren’t just questions.
They were a spark.
An obsession.
A revolution.
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, the path forward went dark. In the stillness, something shifted.
I didn’t want recovery — I wanted a revolution.
But to get there, I needed equipment that didn’t 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.
A revolution for the bold.
What started as a personal quest became something bigger — a movement, a method, a mindset.
A vision became a breakthrough.
That breakthrough became a brand.
Every slide I craft reflects the person it’s built for — born from vision, refined through obsession.
This is personal.
This is precision.
This is TromboneLAB.
