Darkglass Microtubes B7K Ultra V2 Analog Bass Preamp Pedal

The Darkglass Microtubes B7K Ultra v2 is truly a universal tone-crafting machine. This upgrade version features all the versatility and sonic possibilities its predecessor is known for plus amazing features including: a dedicated Footswitch to engage the overdrive section independently, Master Volume to control the overall unit level, three-way toggle switches for each mid control with a total of 6 different mid frequencies, and a dedicated headphone output and balanced direct output with switchable digital impulse-response cabinet emulation, making for an incredibly complete tool for the modern bass player.

Version 2 Upgrades:

- Single user loadable cabinet simulation impulse response
- Micro-USB B port to connect to PC/Mac to load a different Virtual Cabinet
- 3.5mm headphone output with cabinet simulation
- Balanced XLR output with switchable cabinet simulation

Master Volume: 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… read more 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.

Direct Output: 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. read less
