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.

Bass
+-12dB @ 100Hz

Lo Mids
+-12dB switchable 250Hz, 500Hz and 1kHz

Hi Mids
+-12dB switchable 750Hz, 1.5KHz and 3kHz

Treble
+-12dB @ 5kHz

Direct Ouput
Balanced XLR output for connecting the pedal to a microphone preamp, PA system etc.

Ground lift
Disconnects 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 ¼” output.

Cab Sim
Toggle the cabinet simulation on/off on the Direct Output. This switch completely bypasses all digital circuits and allows you to get a zero latency signal when needed.

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

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