Overview

Studio pre with swappable opamps.

The Tone Beast is a great 500-format microphone preamp with loads of gain that effortlessly captures a broad array of sources very well. With top notch CineMag transformers and multiple discrete signal paths, its big, bold, fully-professional sound confounds its attractive price.

The Tone Beast likes to be pushed. With strong input signal and engaged controls, the Tone Beast colorize your signal with a sweetness that could charm the birds out of the trees. The 2 opamps and 2 output transformers at the flip of their switches won't appear to be much different, but as one drives the preamp, its inherent harmonic distortion becomes more present and the unique character of each of these components becomes likewise more apparent. Additionally the Tone Beast is customizable and allows for other opamps to be sourced and easily swapped into the unit.

Unleash the Beast
Warm Audio’s goal was to make a microphone preamplifier affordable without compromising the quality and design parameters that make this type of microphone preamplifier so desirable.
​Home-based musicians and professional studios alike will find the Tone Beast to be a powerful and professional piece of gear that is capable of warming and shaping signals and mixes in a way that is both pleasing and beastly indeed.

Unleash the beast.
