30+ Years of Science, Sound and Imagination  

Jason Harrelson began modifying mouthpieces and trim kits in 1993 and completed his first full-scale trumpet project in 1996. He has since built nearly 1000 experimental brass instruments while maintaining steady production of custom trumpets designed and built for clients individually. In fact, the wait list for a new Harrelson Trumpet averaged over 11 months from 2002 to 2021.

New custom orders are now delivered within 30 days!

Today, most custom trumpets are finished within one month thanks to our streamlined production process. However, many of the art projects shown throughout the gallery required 10 to 24 months from start to finish depending on complexity and scheduling.
