The TB12 Tone Beast Microphone Preamplifier from Warm Audio is a single-channel mic preamplifier this is designed to provide a wide range of tonal options for mic, instrument, and line-level sources. It is capable of up to 71dB of input gain, and employs an output attenuator, allowing you to drive your input signal harder for color and saturation while keeping your signal from peaking.

The TB12 Tone Beast lives up to its name by allowing you to select between two different discrete op amps, two different output transformers that can be bypassed altogether, two input impedance settings for dynamic, condenser, or ribbon mic optimization, and two different capacitors.

The preamp is capable of producing colored, vintage-style tones with early break up and clean, transparent modern tones. Thanks to its front-panel Hi-Z instrument input, the preamp can be used to record DI tracks, while the rear-panel 1/4″ line input allows you to use the TB12 to provide color or warm up previously recorded tracks.

The rear-panel insert send and receive 1/4″ connectors let you integrate an external signal processor, such as an EQ or compressor, into the TB12’s signal flow before the output transformers. The unit features 48V phantom power, a high-pass filter at 80Hz, a 20dB pad, and a polarity reverse switch.


  • Discrete 312 preamp design with Cinemag transformers delivers stellar tone
  • Choice of Melcor or Jensen op-amps for varying character
  • Op-amps are socketed/swappable – add your own op-amps to the mix!
  • Choice of steel or nickel output transformers provide more tonal options
  • Choice of tantalum or electrolytic capacitors for even more character variation
  • Transformer bypass switch provides an ultra-clean character
  • Tone switch allows for variable mic impedance
  • 80Hz highpass filter cuts the mud and rumble
  • 20dB pad tames really loud sources
  • Output attenuation for saturation flexibility of both op-amps and transformers
  • Insert allows the use of inline processors
  • LED VU meter lets you monitor your levels
