The Tone Beast is a mic preamp that likes to be pushed, and when driven hard will colorize your signal ever so sweetly. AT first listen, the dual opamps and dual output transformers (available at the flip of a switch) may not seem to be all that different, but as one drives the pre into harmonic distortion, the unique character of each of these components becomes apparent.

The Tone Beast Black is customizable, allowing users to source and swap in their own opamps if desired. The output control on the TB12 allows you to regulate the signal exiting the preamp even when driving the gain to really hot levels, giving you maximum control.

Have no fear of hurting the Beast, you can push it very hard into full-on distortion if you wish, and these can sound quite nice on electric guitar, bass or anything else that likes some grit.

The different component options in the TB12 are subtle, but when driven into saturation are very noticeable and can make a big difference to the way your final mix will sound.

Home-based musicians and professional studios alike will find the Tone Beast Black to be an extremely powerful and professional piece of gear that is capable of warming and shaping signals/mixes in a way that is full of character, and extremely difficult to find at its price point.
