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.

Improves oral hygiene!
Color: Black
Works great with my Burst toothbrush! Replacing the brush heads is so much easier than purchasing a new toothbrush. I’ve definitely noticed an improvement in my oral hygiene since switching to the Burst products.

Helps With Dry Mouth, Tastes Great and Easy to Keep On Hand
Size: 27 Count (Pack of 1), Size: 27 Count (Pack of 1)
Update: I have already repurchased more! I love the taste and they work so well with a great taste. I’ve been dealing with dry mouth lately, especially at night, and these Biotene Dry Mouth Lozenges have been really helpful. They dissolve slowly and help keep my mouth feeling more comfortable without being overly sweet or strong. The mint flavor is light and refreshing, which I appreciate because some lozenges can taste too medicinal. These are gentle and easy to use throughout the day or before bed if dryness is bothering me. The packaging is also convenient to keep in a bag or on a bedside table. I like that the lozenges are sugar-free and individually sealed in the blister pack so they stay fresh. I included a photo of the lozenge in my hand so you can see the size and what it looks like out of the package, along with photos of the box and blister pack for reference. These are simple, effective, great taste and a good option to keep on hand if you deal with dry mouth.
