    Product Description

    The Warm Audio TB12 Tone Beast offers pro-level quality and control, without the premium price tag. With its high-quality components, the Tone Beast can capture a wide range of sources with clarity and, using the controls, you can tweak just how the pre-amp colours the tone. You can achieve, clear, transparent sound or you can go for vintage tone with warm harmonic distortion - the Tone Beast puts it in your control.

    The Tone Beast features your basic Gain and Saturation controls. Use the Gain control to influence the level of your signal output, from the +29 dB through to +65 dB amplification. Add in the Saturation control to get that classic warm harmonic distortion and compression you can hear on classic recordings through to even aggressive distorted sounds.

    The Tone Section allows you to swap the components in the Tone Beast which in turn colours your tone. The Output Transformer switch allows you to swap between a nickel and steel CineMag USA transformer. Nickel offering that warmer, more vintage-style tone, and steel providing the more modern, transparent tone. You can also bypass these transformers entirely for an even cleaner tone (with a -8 dB drop). Both the op-amps and capacitors can also be swapped in a similar way, with the option of Vintage and Clean sounds. These controls provide a wealth of options for subtly tweaking your tone and become more noticeable when you turn up the saturation. Additionally, there's a +6 dB boost switch for when your signal needs a little extra power when recording with certain mics.

    Very flexible unit which sounds great and has many different options to colour your sound both from microphones and instruments. I've used this on guitar and bass to good effect
