2U of Pure Tube Goodness for Your Rack!

So, let's just get it over with: "Mu" means gain. Now you know. Now let's get on with what it'll do for you. The Variable Mu Mastering Version works wonders on your tracks, coating guitars, drums, bass, and vocals in tube goodness - the kind of goodness that will make or break a track. The Variable Mu Mastering Version is a standout on the stereo bus, and differs from the standard Variable Mu only by the inclusion of detented and logable steps built with 1% metal film resistors on sealed gold-contact Grayhill switches. While it's not a clone of the legendary Fairchild 670, it does share a similar limiting philosophy, imparting a special character on everything that passes through it.

So how does it do what it do? Part of the magic lies in the fact that the Variable Mu Mastering Version is the only true variable mu limiter currently being built in the world. Then there's the innards. At the heart of the peak reduction and compression is a 5670 variable my dual triode. Without getting all science-y, the interaction between the tube and the control voltage is the cause for smooth gain changes. Therein lies the magic!

If you want to use the Variable Mu Mastering Version to add some real color to you tracks, turn up the input and turn down the output. What you'll get is warm, rich tube distortion. A true multi-purpose tool, the Variable Mu Mastering Version is great for recording, mixing, and mastering, delivering stunning results at every turn. If your sound is lacking, inject it with some Variable Mu Mastering Version. You won't be sorry!

Tubes Rule! That's the sentiment EveAnna Manley and Manley Labs screams from the mountain top. And judging from the way Manley Labs gear sounds, tubes could very well rule! All of Manley's gear is designed and crafted in Chino, CA, and nothing but premium components are used. The end result is some of the finest gear you can put in your rack. If you're serious about your sound, get Manley and hear what you've been missing!
