Based on the API 312 preamp's design and sporting premium CineMag transformers, the Tone Beast is already a stellar mic pre. The Tone Beast's real magic, however, lies in its multiple discrete signal paths. With the flip of a switch, you can select different transformers, op-amps, and capacitors and enjoy myriad tones in the process. Push the Tone Beast and enjoy the harmonic distortion it lends to electric guitars, bass, or anything else that needs some grit. Big, bold, and fully professional, you won't find many preamps like the Warm Audio TB12 Tone Beast for under a grand!

Multiple discrete signal paths provide unprecedented flexibility

Experienced recording engineers love how different mic preamps color their sound. They know that by combining different mics with different preamps, they can make every source sound its absolute best. With the TB12 Tone Beast in your rack, you'll be able to do the same, thanks to its unprecedented versatility. The Tone Beast's flexibility is staggering. First, you can choose a Melcor 1731 or Jensen 918 op-amp. The 1731 is very colored and breaks up quickly, while the 918 is fairly clean with just a hint of character. Second, you can choose a 100% steel or 50% nickel transformer. The steel output transformer is more colored than the nickel transformer, especially when pushed. You can also bypass the transformers completely for an ultra-clean tone. Finally, you can choose tantalum and electrolytic capacitors for even more tonal variety.

Coloration — and why you want it

The most coveted vintage consoles and outboard gear weren't transparent. And that's the point behind the Warm Audio Tone Beast. Coloration is, in many cases, desirable. If your mixes sound unprofessional and lacking in vibrancy and depth, you'll love the Tone Beast. Subjective listening tests played a big part in the development of this amazing preamp. Test equipment can tell you only so much, and there's a point in the design process where you just have to let your ears call the shots. You wouldn't mix with earplugs and an oscilloscope, would you?

Top-tier performance and amazing value

Warm Audio gets that, too, and the Tone Beast delivers on both counts. Warm Audio gear is made in the USA and uses only the finest components, such as genuine CineMag input and output transformers. Look at it this way: at this price, you can pack your rack with two or more Tone Beast preamps — perfect for recording live drums or more than one track at a time.

Looks nice, easy to install
Color: Rustic Brown, Number Of Shelves: 2, Size: 22in
This shelf is lightweight, looks nice, and was easy to install. It comes with a little level to help you install it properly. There are plenty of mounting holes to choose from, so it is easy to screw it directly into a stud, or to just use holes that are convenient for you. It comes with a plethora of mounting hardware. I mounted mine a bit high up and chose to mount it upside down so that I wouldn't see the three screws that hold the shelf to the mounting bracket.

The floating shelves are great
Size: 24"W, 2P, Color: White
I finally found a complete set of Japanese tea cups. I had bought 2 in Canada at Sypson and Sears. I had went to visit my family in British Columbia. But I couldn't find the rest of the set. I finally found the rest. My son-in-law installed the four shelves. They look nice and work great.
