Warm Audio TB 12 Tone Beast

The TB12 includes a 1731-style op-amp, which provides a vintage, colored sound, and a 918-style op-amp, which offers a cleaner, more modern response. You can easily switch between them to match the character of your source material.

Yes, the front-mounted 2 MOhm Hi-Z input is specifically designed for passive instruments. It allows you to plug your guitar or bass directly into the preamp to capture a high-quality signal before it hits your interface.

The TB12 features two different CineMag output transformers that allow you to toggle between distinct sonic profiles. One provides a more vintage, saturated character, while the other offers a cleaner, more transparent signal path.

The Tone button engages a circuit that shifts the input impedance and changes the frequency response of the preamp. It adds a subtle +6dB boost to specific frequencies, giving you an extra layer of tonal shaping beyond standard gain adjustments.

Yes, the 1/4" insert point allows you to patch in external processors like compressors or equalizers after the preamp stage but before the output transformer. This gives you more flexibility in your signal chain without needing a complex patch bay.

With a maximum gain of 71dB, the TB12 has plenty of headroom to drive most low-output ribbon or dynamic microphones cleanly. It is well-suited for capturing quiet sources without introducing excessive noise.
