Jeff plays XO/Jupiter exclusively, and is one of their R&D consultants.
Jeff's current main trombone is coming soon, slated for release Q1 2028.
Prototypes pictured below.
XO Medium Prototype, 8
508/525 with trigger. Bell is 8in. yellow-brass from the Fedchock 1634. My leadpipe design.
XO 1632, 7.5
An extra-thick sheet of Rose Brass was accidentally grabbed for this 7.5 bell, serial #00001. Slide is the prototype 508/525
XO 1236 Orchestral, 8.5
the straight 547 slide, will soon have two brothers - 525/547 and 547/563.
The horn you've been waiting for.
"My XO Brass trombones give me complete confidence. The response is centered and instantaneous, allowing me to shift between nuanced studio sessions and soaring Salsa, to Thad Jones 3rd bone parts and combined pit orchestra books, with ease."

XO Professional Trombones
The Prototypes to the left were crafted to slot with Euph-like ease, for efficiency (more sound from less effort), and chameleon-like timbral changes with differing mouthpiece depths. This soon-to-be-available trombone handles everything required of a commercial trombonist. Musicals/Pit Orchestra, Big Band parts 1,2, or 3, Salsa, fusion, whatever you can throw at it!
