Finally, this rare, sought-after, and expensive dual-channel variable-mu tube compressor has transcended its original form so it can transform your mix or master. Simsalabim. 

Magic Bus 
Pricey and prized, fewer than a thousand 670s were ever made, and it was originally used as a mastering limiter for vinyl. With a characteristic vibe heard from Motown to Abbey Road, the unit is known for adding sound and harmonic distortion even when you don’t do a thing. If you push it, it gives pump but – at its more subtle settings – the 670 is great for gluing things together in a warm, musical way. You can see why it’s useful on everything from the mix bus to drums, vocals, and electric guitars, and has earned its place in top studios worldwide. 

What’s cool about variable-mu? 
Variable-mu compression uses tubes to alter gain, and the compression ratio changes dynamically in response to the signal level. The result is the harmonically rich and musical compression that has made the original 670 legendary. This style of vintage processing is great for gluing things together with analog warmth and cohesion, making it ideal for mastering as well as mixing. 

New Magic
To create our Bus Processor 670 plug-in, we took the finest elements of the original and added our own wouldn’t-it-be-cool-if ideas to make a totally unique tone machine. Starting with full control of saturation points with dedicated knobs for tube and transformer saturation, and a calibration knob to influence the unique compression-dependent saturation of the variable-mu architecture. We also included sidechain options that give you control over filters, tone shift and mono/stereo linking, as well as separate outputs for M/S channels. Then there are the new spatialization features that include air band, mono maker, and stereo widening knob. 

Full-featured but dead-simple to use, Bus Processor 670 lets you find the magical sound of the 670 for yourself, with a workflow fit for your modern studio.
