A Deeper Look At UnderTone's History

  • Video-3_2x_1.jpg

    Eric Valentine, owner and founder, created UnderTone Audio as an outlet to build flexible gear for engineers, mixers, and producers outside his own studio, Barefoot Recording. Aside from cutting records for famous acts like Queens of the Stone Age, Slash, and Nickel Creek, he develops gear for audio engineers who want studio-grade hardware without investing in a full console. UnderTone Audio only uses Class-A circuitry and high-end mic preamps from its custom recording consoles to make products that outperform the rest.

  • The MPEQ-1 was the first creation designed under the banner of UnderTone Audio. This versatile box is a 19-inch rackmount Class A mic preamp, equalizer, and DI all in one. Like other products from UnderTone Audio, the MPEQ-1 is vintage console circuitry in a single box packed with the brand’s custom mic preamp and tons of options: I/O pads, bypassable input or output transformers, impedance switching, and plenty of ways to pull rich sonic color out of every channel. The mic preamp also has incredibly low distortion levels for projects that require the cleanest sound possible. The MPEQ-1 goes far beyond what any EQ plugin can do.

    UnderTone Audio’s UnFairchild 670M II replicates everything extraordinary about the classic Fairchild circuit that has been used on countless records throughout the decades. The basis of its design is simple, yet it can produce quite a few different flavors of compression. UnderTone Audio added unique improvements to combat limitations of the original Fairchild. At its core, the UnFairchild 670M II is built with improved circuitry for an overall longer lifespan. It sports six original preset Time Constants and four variable Time Constants (attack and release), MS function, side chain processing, a true bypass, fine adjustment of left/right balance, user adjustable DC Threshold, and Feed-Back vs. Feed-Forward functionality. The UnderTone Audio UnFairchild 670M II is fully capable of handling just about every compression task for any music genre.

  • Everybody needs a reliable mic preamp; the MPDI-4 fits the role perfectly. It’s a single rack, 4-channel microphone preamp designed using the same technology and concepts behind classic recording consoles. It’s often difficult to push a microphone preamp to get rich sound without clipping but, the onboard output pad on the MPDI-4 drops the output by 10db for plenty of room to drive it without clipping the front end of your digital workstation. From a design perspective, this is made possible by altering the ratio of the output transformer. The input and output transformers are bypassable with controls on the front of the device for added convenience. With the MPDI-4, you’ll be rewarded for pushing the limits of sound.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.

From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
