Darkglass Microtubes B7K



The Microtubes B7K takes the powerful dynamic saturation circuit of the B3K and adds a four-band equalizer and a balanced line driver for even greater versatility. Designed for both studio and live use, it will take your direct sound to a whole new level.


Level: Sets the volume of the overdriven signal.
Drive: Sets the amount of saturation in the overdriven signal.
Blend: Mixes the clean input signal with the overdriven signal. The clean signal remains at unity gain while the volume of the overdriven signal is set by the Level knob, allowing for fine control of the blend ratio.
Grunt Switch: Sets the amount of low frequency content to saturate by selecting between three different bass boost levels before the clipping stage.
 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!
Low: +-12dB @ 100Hz / Low Mid: +-12dB @ 1kHz
Hi Mid: +-12dB @ 2.8kHz / Treble: +-12dB @ 5kHz
Direct Output: A balanced version of the ¼” output, useful for running into PA’s or studio mixing consoles.
Microtubes B7K Artist
“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)
