$ 399.99

The Darkglass Electronics Microtubes B7K Ultra V2 Preamp, DI, Tone Shaping Workhorse features all the versatility and sonic possibilities of the first version plus: (1) Single user loadable cabinet simulation impulse response. (2) Micro-USB B port to connect to PC/Mac to load a different Virtual Cabinet through the Darkglass Suite. (3) 3.5mm headphone output with cabinet simulation. (4) Balanced XLR output with switchable cabinet simulation.

The Microtubes B7K Ultra V2 bass preamp a pre-amp, a 4-band EQ, with Attach and Grunt instant boost, plus an excellent DI. The Microtubes B7K Ultra V2 uses the same quality internal components known to Darkglass bassists from around the world.

Comes with a FREE compatible power supply!

Darkglass Suite

Download the free Darkglass Suite software from www.darkglass.com/suite to configure the pedal, load new impulses and download firmware updates.

Darkglass Suite comes with a selection of cabinet IRs made by some of Darkglass's artists. It also allows you to load your own IRs in WAV and AIFF formats and organize your IR files. See the online manual of Darkglass Suite for more information.

Your vision, their gear.

Controls

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 and processed signals. The clean signal remains at unity gain while the volume of the overdriven signal is set by the Level knob, allowing for fine mix tuning.

Level: Sets the volume of the overdriven signal.

Drive: Sets the amount of gain 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 Output: A balanced version of the ¼” output, useful for running into PA’s or studio mixing consoles.

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.

WARNING: When the pedal is on bypass the master volume does not affect the headphone volume. In this case the total volume is adjustable in Darkglass Suite. With sensitive headphones the bypass volume can be very loud if not adjusted.

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.
