AR-1 is a variable-mu tube compressor whose roots are in the raucous sound of the rockin' American 50's, yet it enjoys a posh British image thanks to its use at Abbey Road Studios in late 60's, notably on the later Beatles and earlier Pink Floyd records. Kush painstakingly captured the sweet breakup of AR-1's beefy tubes being driven into the dirt, then added more than a half dozen significant UI and functional enhancements. The resulting emulation is every bit as chunky as the original, and 10x more flexible.

The real magic of AR-1 lies under the hood, with new algorithms that step Kush's digital compressor technology forward. A common complaints about plugin compressors is that they're "too fast". Even when a plugin's attack time is identical to the hardware, it generally sounds markedly different, resulting in transients that are excessively bright while lacking in low end impact. Kush addressed this by obsessively tuning not just the speed, but also the taper of the attack and release. The result is a gentle beast that's still capable of cooking a sound to a deliciously charred crisp. The typically overused audio marketing terms 'Warm' and 'Smooth' now really do apply.

AR-1 is a great Vari-Mu with very nice tones. I like how it works with transients.

I use it often in my projects, it gives a nice analogue feel with pleasant saturation that can vary from dark to bright tones. Recommended to anyone who is looking for a cool Vari-Mu Comp.
