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.


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.


Sets the volume of the overdriven signal.


Sets the amount of saturation in the overdriven signal.

Direct Output

A balanced version of the ¼” output, useful for running into PA’s or studio mixing consoles.

Disconeccts the signal ground on the Direct Output to break any ground loops. Set this switch to either position that has less noise. The switch does not affect the 1/4" output.

Cab Sim

Toggle the cabinet simulation on/off on the Direct output. This witch completely bypasses all digital circuits andallows you to get a zero latency signal when needed.


B7K Ultra has an internal stereo headphone amplifier capable of driving a minimum load of 16 ohms from the 3.5 mm stereo jack. use the Master volume control to adjust the level.


A Micro USB B connector allow you to connect the pedal to PC/Mac to load cabinet simulation impulse to the pedal and control various other settings.
