Warm Audio TB12B Tone Beast Discrete Microphone Preamp

The TB12 Tone Beast Black stands as a Swiss Army knife of professional preamp design, packed with loads of gain and an arsenal of tonal options that can handle virtually any source you throw at it. Built around top-notch CineMag transformers and multiple discrete signal paths, this fully professional unit delivers big, bold sound that punches well above its price point. Home-based musicians and professional studios alike will find this an extremely powerful piece of gear that warms and shapes signals in a way that’s genuinely pleasing to the ear.

This mic pre thrives when pushed hard, colouring your signal with sweet harmonic character as you drive it into saturation. The 2 opamps and 2 output transformers might seem subtle at first flip of their switches, but their unique personalities become apparent when you push the pre into harmonic distortion territory. What sets the Tone Beast Black apart is its customisable nature – users can source and swap in their own opamps to further tailor the sound to their needs.

The fully discrete, high-voltage design utilises CineMag USA transformers and isn’t afraid of being pushed to its limits. You can drive it hard into full-on distortion without fear, making it particularly effective on electric guitar, bass, or anything else that benefits from some grit. The output control gives you maximum flexibility, allowing you to limit the signal exiting the preamp even when pushing the gain to scorching levels, ensuring you maintain complete control over your sound.
