The Microtubes B7K takes the powerful dynamic saturation circuit of the B3K and adds a four-band EQ and balanced line driver for even more versatility. Designed for studio and live use, it will take your direct sound to a whole new level.
Level Adjusts the volume of the distorted signal.
DRIVE Adjusts the amount of saturation of the overdriven signal.
BLEND Mixes the clean input signal with the distorted signal. The clean signal remains at unity gain while the volume of the overdriven signal is adjusted by the Level knob, allowing precise control of the mix ratio.
Grunt Switch Grunt Adjusts the amount of low frequency content to overdrive by selecting between three different bass boost levels before the clipping stage.
Attack Switch Adjusts the amount of treble content to overdrive: The “Boost” setting emphasizes the clarity and presence of treble content. The "Flat" position leaves this register intact while the "Cut" position will reduce the amount of distorted high frequencies. This new addition helps keep the high end of the signal under control, especially useful when playing with new strings and/or cabinets with tweeters! Low + -12 dB at 100 Hz Low Mids + -12 dB at 1 kHz Hi Mids + -12 dB at 2.8 kHz Triple + -12 dB at 5 kHz Parallel Output A passthrough for your input signal, useful for parallel processing. Direct Output A balanced version of the ¼” output, useful for running into PA or studio mixing consoles.
