The Jerome Callet "Jazz" Trumpet and the Callet "Jazz" Flugelhorns are back in production! These tried and proven modern super horns are still made with the original lead pipe and bell tooling as a starting platform, carrying on with the tradition of innovations. 2017 ushered in some improvements to these already great instruments. The Generation II series Callets!

- The Callet "Jazz" Gen II trumpet with the original .020' yellow brass bell.
- The first ever Callet "Jazz" LT trumpet with the .017' lightweight bell.
- The Callet"Jazz" Flugelhorn Gen II with a new lead pipe and enhanced resonance.
- The all new Studio Artist .464 and Studio Artist .464 LT by

What's new? The lead pipes are meticulously drawn with a new and improved method started in 2017. Then the venturi is carefully set to the exact thousandth of an inch by Lee Adams and carefully hand fitted to the special heavy receivers here at the custom shop in Atlanta which includes our exclusive new ERT (Enhanced Resonance Technology) the lead pipe venturi size is now stamped into the underside of every receiver.

Then the lead pipes are sent to Kanstul where our Jazz bell mandrel remains and the bells, valves, and assembly are completed.
Then back to the shop in Atlanta where each trumpet receives a PRV precision valve alignment with our exclusive port balancing. Valve port edges and valve guide contact points are polished. All internal parts are weighed, marked and strategically placed to create the best combination of player feedback and projection.

- The heaviest bottom cap (marked inside) when on the second valve gives a good combination of player feedback and projection.
- The heavier bottom cap can be moved to the third valve to increase projection and the slots become firmer with less player feedback.

Play testing by Lee Adams with special tweaking done by George Rawlin. Each horn receives several hours of refinements after the initial assembly to optimize response and resonance.

New for 2017 The Callet Jazz Gen II has three standard lead pipe venturi options .346 .348 and .350.
Add to that 2 new main tuning slide options and you can create a trumpet that works for YOU and all of your different playing requirements! 5 different lead pipe gap options to chose from during custom fittings for full customization.


All Northern Brass Mouthpieces are Mathematically and Acoustically Designed.
Originally designed and manufactured by GR as custom designs to help solve the problems inherent in mouthpieces designed for upper register work, and for efficient all around playing.

Very high alpha angles can not be played well by most players the sound becomes brittle and articulations are very sloppy. Very low alpha angles can make articulations harsh and sound very tinny.
GR designed the NB mouthpieces keeping in mind first, an alpha angle which is playable by the majority of players. This unique alpha angle was developed in order to keep the chops supple and free to vibrate, yet provide support and fast, clean articulations. Players will experience a much broader spectrum of sound with NB compared to other commercial / lead designs. Higher as well as lower overtones are full and in focus.

Northern Brass Mouthpieces are known for their solid upper register, but not at the expense of producing a good sound in the low and middle registers, pointed articulations, and acrobatic flexibility make the NB some of the most versatile mouthpieces available.
After trying virtually everything on the mouthpiece market in recent years. I kept returning to the original Northern Brass models and GR made mouthpieces as unsurpassed in quality, consistency and playability. So we are thrilled to have GR the world leader in mouthpiece technology making the Northern Brass line for us. With 6 new models with the #3 rim added to the line for 2017. This expands the line to fit even more players.
