The Box Beta is a combination of 2 bosters ( Rackle boost & mk3.2) that are run in sequence. You can go from a nice light boost to a full on savage boost. Tread lightly as it will boost anything its feed into it. I would recommend this unit be used at the end of an effects chain to bring life back to some of that signal that was lost in the chain. The D2 switch engages the second boost. The V switch engages a hard clipping option if you want to turn your boost into a dirty overdrive.

Overall great unit for pedal lovers and even pedal haters have coomented in this units versatilaty.
