Here we have a pre owned Darkglass Microtubes B3K CMOS Bass Overdrive Pedal.  Designed in Finland.   The Microtubes B3K is designed for the bass players with a natural sounding overdrive.  Controls for Level, Drive, Tone, and Blend.  Buttons for Grunt and Mid-boost.  This pedal is powered by a 9v dc power supply (not included).  This pedal is in very good condition with some light marks on the exterior.  Tested and working perfectly.  We do not have the original box so you will receive the pedal only. Thanks for looking an happy buying!
From Darkglass site....

• The natural dynamics and organic compression of vintage tube amps and tape machines
• Level control sets the volume of the overdrive signal
• Drive control sets the amount of saturation in the overdrive signal
• Blend controls bring your clean signal back in
• Grunt switch lets you select the amount of LF content to be saturated
• Mid boost button brings back frequencies that can be lost with other drive pedals
• Power requirements: regulated 9-volt DC adapter with center-negative plug

With the Microtubes B3K v2, you get all the features of the original, with the ability to restore the mids for natural character. The attack switch has been replaced by the tone knob, giving much more control of the higher harmonic content (3 kHz to 8 kHz). The grunt switch is still present, as you would expect. The addition comes in the form of a mid boost, giving you a subtle 6dB boost from 300 Hz to 1 kHz to help you cut through a bit more. 

Fundamentally, the Microtubes B3K is the same pedal we designed nearly a decade ago, aimed to give you a perfect combination of brutality and clarity. You can guarantee that this pedal will deliver defined and powerful saturation in an intuitive format.
