    The tb 12 has an incredible ability to breathe some analog life into anything that passes through it. I've used this preamp on a lot of different things recently and its just a jack of all trades. I like it particularly for getting a little grit out of a room mic on a kit. Overall, a really wonderful preamp, with tons of versatility, for a great price.

  • Great PreAmp

    Like many people, I do extensive research before making a purchase. I learned through jtrying different preamps that the API sound best suited my vocals. The TB12 does a great job getting that sound plus it has lots of great options. Really happy with this.

    Killer preamp! Tons of subtle and tasteful coloration. Drive it hard to really hear the tonal characteristics of the different output transformers and capacitors. Very low noise with lots of details in the mid range. I suggest getting this preamp if you have some years of recording under your belt.…

  • So many issues

    Verified Purchase

    After 6 months the unit started having a scratchy output pot. The x18 amp stopped working. And now it picks up noises in my control room and they are printed to my tracks. Never had this many issue with anything I have purchased. It only gets a 3/5 because when it did work it sounded amazing.

    Very useable options all over this wonderful preamp. It's round and thick sounding. Being modeled after an API 312, it has its own tonality. Definitely in the same category as any of the other high end brands.
