New from Groove Masters Percussion: The Tubolo.

Take a typical tube-style drum, cross it with a Brazilian Rebolo and you have perhaps one of the most versatile hand percussion drums yet. The Tubolo features Groove Masters' trademark AirDrum system of vents along the bottom of the drum. This allows the drum to project sound without the need to tilt or place the drum onto a stand. Also makes for a lightweight drum. The internal, specially designed Bass Port creates deep and resonant bass tones. Tune them to different pitches to use like congas. 

The playing surface is made from Napa vinyl, which creates a mellow sound and is easy on the hands.
