The upgraded Microtubes B7K Ultra 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.

This creation differs greatly from our previous preamplifiers and overdrives: it is fully operational amplifier based and has two distinct distortion circuits (Alpha and Omega) which can be selected or blended using our Mod knob. This unusual control, in conjunction with the toggle switches and 3 active band equilizer makes Alpha · Omega the most flexible among our designs.

The character and core of the Microtubes B7K remains the same, still retaining the powerful dynamic saturation circuit of the B3K and adds a four-band equalizer and a balanced line driver for even greater versatility. Designed for both studio and live use, it will take your direct sound to a whole new level.

With the double distortion engine (Alpha and Omega), the Alpha·Omicron delivers unparalleled versatility, harmonic rich and bone-crushing sound. Designed for bassists in need of a preamplifier to be distinctively heard in any musical context.

Fundamentally the Microtubes B3K is the same pedal we designed nearly a decade ago, aimed to give you a perfect combination of brutality and clarity. You can guarantee that this pedal will deliver defined and powerful saturation in an intuitive format.

The Duality is a unique fuzz pedal that contains two discrete fuzz circuits—a gated saw-tooth wave and a raunchy high-gain sound—which can be mixed together to yield a vast selection of distinct sonic textures.
