The Manley Labs VOXBOX is an all-tube channel strip that may well be your "last stop" voice processor, but it's also set to make the most out of virtually any source you throw its way. The VOXBOX shares its fully featured microphone preamplifier design with Manley's acclaimed Mono Microphone Preamplifier, offering a whole lot of headroom and Class A vacuum tube tone. What's more, the smooth compressor section is a perfect blend of Manley's best-selling Variable MU and the opto-design of their ELOP. All of these features, in addition to a flexible Pultec-style mid frequency equalizer, de-esser/limiter section, and stereo link function, make the VOXBOX a true sonic studio workhorse.

I've experienced using the VOXBOX at the studio in my school and just as it is one of my professor's favorites to use on drums it has become my favorite as well. At the school, we don't have a great sounding drum set but the VOXBOX definitely works it's magic to give us a recording that sounds like we have the best sounding drum set. Couldn't help to notice the title of the previews review and it's perfect.

I've used the VoxBox once in a live situation, ever since I wish to buy one for my studio, but don't have the budget. The preamp sounds clean and with tons of headroom (used it on a beatbox through wireless SM58). I liked the compressor, which let me control the dynamics without diminishing the punch; also the Pultec style EQ made the beatbox very powerful. I also liked the de esser that allowed me to control the hi hats compared to the snare sounds. I can imagine using it on vocals, bass guitar, and probably on anything where a clean dynamic sound is asked for. It's also very flexible, you can use everything, or use the preamp out only, and also insert any other processor, and use line input while mixing. I love it !

I've had my Voxbox for 4 years now... I always wanted one and got in a position to do it. It is absolute "taste" in a box. I can't tell you how many times people have complimented it AND come back for more. The VoxBox is actually 2 separate unites that you can link together with a switch OR (here comes the game changer) you can separate the two in to a Mic pre/comp and 2, a (mid-pultec style) eq and de-esser. So you can run two different sources in to either just the mic pre and a different source can utilize the eq section at the same time. I have a chain where I bypass the comp, come out of the mic pre and in to a Distressor and BACK to the voxbox eq. I just got a retro double wide so I'll try that too. Obviously any compressor can then slide in to the voxbox chain with a simple XLR or TRS. I have a UA 2-610, an Avalon 737, Shadow Hills Mono Gamma, Black Lion Audio 173 and Autuer mk ii. I still come back almost every time when I need to go big fast. A couple tips... The lowest left knob is only labeled as "input" this is an attenuater not a GAIN. Working out the "gain" knob in conjunction with the attenuater you are then able to tastefully hit the tubes hard or be as soft and clear as you can with it. We put everything in bypass on the unit and just use the mic pre almost daily when using DI's... DI sources are insane when run clean like this. I couldn't say enough about this unit. I could sell almost everything and just use this. It's also cool that if you really look at the VoxBox you can actually see the "V" and the "B"
