Whether The Rasmus, Him, Nightwish or many more - Finland is one of the European music nations with an international impact far beyond the continent. So it is only logical that high up in the north there are also manufacturers who develop the necessary tools in top quality. Darkglass founder Doug Castro had already made a name for himself with various bass preamps like the B7K or the Vintage Microtubes with greats like Tony Levin, Alex Webster or Bootsy Collins. However, resting on his successes does not correspond to Castro's ambitions and self-confidence as head of Darkglass and bassist in his own person.

In the Microtubes B7K Ultra, the preamp idea has been constructed to the last consequence. The sound engine was taken from the first generation B3K, the tone control was already found in the bigger brother B7K, which brought a lot of optimisation for recording and Bühne in terms of features. The flagship of the series allows you to leave the distortion section out and process the clean channel with the tone control. For the realisation of this idea, a master control could not be missing, which is why the Ultra had to change to a larger cabinet. In addition, it has a micro-USB and a headphone connection. The cabinet simulation of the XLR output is switchable.
