Product Description

The Darkglass Microtubes B7K Ultra V2 Analog Bass Preamp features all the versatility and sonic possibilities its predecessor, including a tone-sculpting four-band EQ, blend, and level controls. You’ll also enjoy these amazing features, including: (1) A dedicated Footswitch to engage the overdrive section independently. (2) Master Volume to control the overall unit level. (3) Three-way toggle switches for each mid control with a total of 6 different mid frequencies, and (4) a dedicated headphone output and balanced direct output with switchable digital impulse-response cabinet emulation, all making for an incredibly complete tool for the modern bass player.

Technical 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
The B7K Ultra V2 now is truly a universal tone-crafting machine!

Darkglass Microtubes B7K Ultra V2 Bass Preamp EQ and Boost Pedal Features
  • 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 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.

Gread pedal. I am using it on my acoustic upright bass. Does exactly what I need. I had to boost the piezo pickups and this did the trick. Great looking box. Built solid. Knobs and buttons are heavy duty. Darkglass always makes a super product and this is no exception. Im looking forward to getting more pedals from these folks as I need them. You will need your own power supply as it does not come with one.

One of the Best Purchases I’ve Ever Made

Product Review

I never even knew this thing existed until a friend told me about it. I decided, on a whim, to get it. I couldn’t be happier. If you want to not worry about setting up mics to record bass. Or not having the full sound because you’re going through a DI; get this preamp! It’s great for both studio and live! The software is fantastic! I’m not going to lie, this is the first time I’ve ever truly enjoyed playing bass in the studio.

Finally Darkglass has got it right!!!

Product Review

In the age of modeling and profiling, the important aspect in this pedal for one is blending in the distortion with the preamp. As well as the options with the eq. If you’re looking for endless possibilities within tone, Darkglass is the way to go.

Amazing, went ever play without it!

Product Review

Awesome, awesome, awesome! The control over tone shaping and the added overdrive channel are the best out there. Throw in the cabinet IR's and mid frequency blend and controls and you have a device that is not only second to none but also worth every penny. I now set my amp eq straight up because this thing does all my eq control. Blown away!

Great tone. Bought it to use as a di for recording. Ended up also using it as a headphone amp for silent practice.
