Darkglass Solid Series | Microtubes B7K v2
Design &Tone - Perfected
Tone crushing overdrive and super transparent modern sound is the essence of the B7K. One of the most acclaimed Darkglass pedals in the bass community, it doesn't compromise the original sound of the instrument, but it enhances its presence in the mix.
With the Microtubes B7K v2 you get all the features of the original, with the ability to better sculpture your tone: on the low mids you have the option to change the centre frequency from 1KHz to 500Hz, and on the high mids you have the option to change the centre frequency from 3kHz to 1.5kHz. This will enable you to tailor your absolute dream distortion tone.
The character and core of the Microtubes B7K remains the same, still retaining 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.
