CMOS Bass Overdrive.

The Microtubes B1K is a phenomenal tribute to one of our most legendary distortion circuits in a compact and intuitive format. We are proud to introduce our Microtubes B1K distortion pedal, the first of its kind from an all-new lineup.

Front | Level

Sets the volume of the overdriven signal.

Front | Drive

Sets the amount of saturation in the overdriven signal.

Back | Blend

Mixes the clean input signal with the overdriven signal. The clean signal is fixed at unity gain, while the volume of the overdriven signal is set by the Level knob, allowing for fine control of the blend ratio. Turn clockwise to blend in the clean signal.

Back | Tone

Controls the high frequency content of the sound. A variable low pass filter from 3 kHz to 8 kHz. Turn CCW for a brighter sound.

Back | MBoost

Gives a subtle 6 dB boost from 300 Hz to 1 kHz to help you cut through the mix.

Back | Grunt

Provides a low-end boost to massively thicken your sound when engaged.

WARNING:

The Microtubes B1K has a current draw of 30 mA. Only use a regulated 9V DC adapter with a center-negative plug. Due to ecological reasons, it does not accept batteries. Unregulated power supplies and/or higher voltages may result in suboptimal noise performance and even damage your unit, voiding the warranty.
