The ‘J4H’ tenor trombone is based on the model ‘J4’. Only the fourth-valve is different which changes the instrument’s geometry. The valve used is a Hagmann valve, which is characterized by easier air passage and therefore decreased turbulence resulting in improved response and a richer tone. This trombone is right at home in a classical orchestra.
