 Attack Switch: Sets the amount of treble content to saturate: The “Boost” setting emphasizes the treble content extra clarity and presence. The “Flat” position leaves this register untouched while the “Cut” position will reduce the amount of high frequencies being saturated. This new addition helps to keep the treble portion of the signal under control, specially useful when playing with new strings and/or cabinets with tweeters!

Artists 
“The people at Darkglass Electronics must be bass players, because it’s the first time I’ve used a drive pedal that not only sounds right, it FEELS right.” 
Billy Gould (Faith no More)
“With the B7K, Darkglass have totally nailed the perfect balance of aggression and clarity. I can’t believe how much distortion you can dial in without compromising the note fundamental or sheer amount of low end. The 3 different modes are all distinct and cover a large range of sounds – whether live or in the studio, you’ll never need another bass overdrive pedal!” 
Adam “Nolly” Getgood (Periphery)
“The Microtubes B7K is an absolute must-have tool for any serious rock bass player. It’s clarity, power and respect to the instrument’s tone are unparalleled!” 
Felipe Andreoli (Angra)
