Front Features

Master
Whereas the Level Knob controls the output of the overdrive section the Master volume adjusts the overall volume of the unit. Ideal for fine tuning the output on clean mode. It also serves as a DI level control.

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.

Level
Sets the volume of the overdriven signal.

Drive
Sets the amount of saturation in the overdriven signal.
Attack Switch
Sets the amount of treble content to saturate: The Boost setting emphasizes the treble content extra clarity and presence. The Flat position leaves this register untouched while the Cut position will reduce the amount of high frequencies being saturated.
Grunt Switch
Sets the amount of low frequency content to saturate by selecting between three different bass boost levels before the clipping stage.

The Microtubes B7K Ultra has a current draw of 120mA. Only use a regulated 9V DC adapter with a center-negative plug.

Unregulated power supplies and/or higher voltages may result in suboptimal noise performance and even damage your unit, voiding the warranty.
