The Microtubes B7K V2 bass preamp pedal from Darkglass Electronics is so much more than an excellent DI. It's also a pedal-sized preamp and aggressive-sounding drive. The Microtubes B7K V2 employs the same dynamic saturation circuit and 4-band EQ and balanced line driver that has put Darkglass on thousands of bassists' boards. Yet, the addition of two mid-frequency selector switches, as well as the Grunt and Attack controls give the V2 unparalleled tonal shaping abilities. And dual outputs make parallel processing and running your signal to a PA or mixing console a piece of cake.
