Warm Audio TB12 Tone Beast Microphone Preamplifier

With Warm Audio's version of the classic Melcor 1731 and Jensen 918 op-amps, and 71 dB of gain on tap, this Beast lends character to any source you plug in.
The Warm Audio TB12 Tone Beast microphone preamplifier offers you a rainbow of tonal colors to choose from. Switch between Tantalum and Electrolytic capacitors for different capacitor character, 100% steel and 50% nickel CineMag output transformers for a different transformer sound, or go transformer-less with a transformer bypass switch -- you've got many discrete signal paths at your fingertips. As if that isn't enough, you also have either the classic 1731 or the 918 style op-amp to choose from. Other must-have features on this beast include a polarity reverse switch, an 80 Hz high-pass filter switch, an easy-to-read LED meter, an insert for inline processors, and a -20 dB pad switch. This preamp is a total steal for what it'll bring to your recording setup.

Watch Grammy-nominated producer Joe Carrell discuss recording The Voice's Johnny Gates and Kayley Hill with the TB12 Tone Beast in Black:


An Almost Endless Number of Paths for your Discrete Signal

Choose your destiny -- your TB12 gives your multiple paths to choose from to give your discrete signal a different character through each avenue. The Melcor 1731-style op-amp breaks up evenly and has a nice color to it when your start pushing your signal, and your Jensen 918-style op-amp has a little bit more cleanliness to it. Your 50% nickel transformer pushes your higher and lower frequencies a bit more, while the 100% steel transformer will give your signal more color and read more body overall. You can also bypass both transformers, resulting in an 8 dB level loss and a cleaner signal.

Using Your TB12's Circuitry to Tweak Your Sound

As if the Tone Beast's wealth of different paths weren't enough, you can also swap your capacitors for more subtle tonal differences. Tantalum capacitors are used with the "vintage" setting, and electrolytic are employed for the cleaner setting. The difference is very subtle and can be better heard when you push your TB12 further into distortion.

Mad Line of Controls

You'll get addicted to the degree of fine-tuning that your TB12 lets you play around with. Your input control section has all the usual suspects: a Hi-Z button for your input, a line button, your phantom power switch, your 20 dB pad switch, a reverse polarity switch, and your 80 Hz high-pass filter switch. Your tone control section hosts your op-amp switch, a +6 dB tone button, your vintage/clean capacitor button, your output transformer bypass button, and your steel/nickel output transformer selector switch.

Finally, your gain and saturation section features a gain control and an output level control next to an easy-to-read and colorful LED UV meter. You can drive this baby pretty hard, while keeping your output signal low enough to keep things in check once your signal leaves your TB12. Using your tone control section in conjunction with your gain and saturation section, you can manipulate your signal more with this Tone Beast than just about any other preamp you're likely to find in your rack.

High-end Performance at a Steal

You'll struggle to find another preamp that offers so many settings and features in this price range. Your Warm Audio TB12 Tone Beast takes your signal and pumps it through a confident collection of optional paths to give your sound a wide scope to explore. You can dial in anything from a subtle boost to an intense wall of fuzz and distortion. With this bad boy, you'll be exploring sonic options for hours on end.

"Another great product from Warm Audio!"
Verified Customer zZounds has verified that this reviewer made a purchase from us.
Is it an API? No. Is it close? Yes, and I have heard API 312 pre-amps that don't sound like other API pre-amps. I have had this for awhile now, and I find it excellent. The price-point makes it easier to do stereo pairs, if desired. I can drive it dirty, or make it very clean. It is flexible, and easy to use. I have used it on vocals (though for my voice, I like my LA-610 MK II better), but it shines on guitar and bass. I love the sounds I get be it with my EVH 5150, my Boogie, or my Randall. It is also great with my WA76 and Sans Amp RBI if I want a fat bass sound for grimy, modern blues. All in all, great product. Don't be scared by the price, it is far from cheap from a sound or quality standpoint. I only contacted them via email to ask a question, and they responded in less than 15 minutes. I give it four-stars for WOW factor only because I hate orange, but that's my problem.
Musical Background:
I have been playing guitar, bass and keys for over 40 years. I used to play professionally, but only write and record now.
Musical Style:
Blues trained, but my iTunes account goes from Robert Johnson to Dream Theater, Maroon 5 to Pantera, Spyro Gyra to Steve Vai. NO
