Easy Sound Control

You can control and shape your sound with Boss' new Total Sound Control. This allows you to change the sound of a drum kit with specialised effects. You can adjust the 3-band compression for a punchier sound, shape your tone with the parametric EQ, or even add reverb with the Ambience effect.
