Preamps offer different things to different people. Some may want clean, uncolored tones while others may desire plenty of character and tone-shaping flexibility. If you’re one of those who wants the best of both worlds, then the Warm Audio TB12 Tonebeast is going to make you quite happy.Providing up to 71dB of gain, the TB12 can handle whatever you throw at it and allows its character to come alive when driven into harmonic distortion. While changes are subtle at lower volumes, simply choose between the TB12’s unique sound-shaping features while saturating the input level and you’ll immediately notice the difference in tonal characteristics of the interchangeable transformers and opamps.Instruments and vocals will benefit equally from the performance of this truly powerful preamp. From home studios to professionals on the road, the assortment of tones and unique functionality of the TB12 Tonebeast could only have been achieved previously through an assortment of additional preamps.
