Warning
The Microtubes B3K has a current draw of 20mA. 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 subopti-
mal noise performance and even damage your unit, voiding
the warranty.

Controls
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.
Tone: Controls the high frequency content of the sound. A
variable low pass filter from 3kHz (ccw) to 8kHz (cw)
Level: Sets the volume of the overdriven signal.
Drive: Sets the amount of saturation in the overdriven signal.
Grunt: When engaged provides a massive low end boost to
really thicken your sound.
Mid Boost: Gives a subtle 6dB boost from 300 Hz to 1kHz to
help you cut through a bit more.
