Welcome To The Stream


The InfiniSphere™ is the first trombone created specifically for use with electronics.  Designed by Justin McAdara and created by B.A.C. Musical Instruments, this new instrument will open up a whole new palette of sonic colors and create a road-worthy instrument that can be used on a daily basis.


Removable sphere

The removable sphere creates an incredibly free-blowing acoustic deadener and allows the trombone to play like a regular trombone but without the issues of feedback from a separate microphone or faulty jacks from practice mutes.
