Selling my Warm Audio TB12 Tone Beast, lightly used in a smoke-free professional studio. There are a few minor scratches on the top from being taken in and out of the rack. This versatile single-channel preamp delivers everything from clean, punchy tones to rich analog saturation, with selectable op-amps and output transformers for dialing in different tonal flavors. Great for vocals, guitars, bass, and drums, with an 80Hz high-pass filter to keep unwanted low-end rumble under control.
