- Separate Drive control to add classic color of the original tube unit, or remove it for crystal clear, smooth vari-mu signal crushing
- Knee control to mimic classic “soft knee” vari-mu compression, or reduce it for more aggressive “hard knee” effect
- Classic Pre-, Post- and Gain Reduction metering
- Output level control and Bypass switch
Product Overview
The Model 660 X Exciting Compressor is an accurate virtual 660-style vari-mu compressor with some very unique features. In 1963, engineer Lawrence Horn introduced the “Exciting Compressor” technique to the Pop world, which involved boosting a large amount of 5-6kHz, then crushing that signal with a 660 compressor and bringing it back up on the board in parallel with your original, unprocessed track. It was a favorite on vocals and drums, and it was used on some of the most classic tracks of the 1960’s.
Carefully modeled from an original unit, the Model 660 X Compressor captures and recreates that sound. In addition to the classic 660 controls – Input Gain, Threshold and Time Constant switch, along with Pre-, Post- and Gain Reduction metering – the Model 660 X has an “Excitement” section that allows you to boost anywhere from 1 to 10kHz up to 12dB, coupled with a Mix control that lets you operate the effect in parallel.
They’ve added a separate Drive control to add the classic subtle color you get from boosting the Input Gain of the original unit, or minimize the Drive for crystal clear, smooth vari-mu signal crushing.
Additionally, we’ve added a Knee control to mimic the classic “soft knee” vari-mu compression, or reduce it for a more aggressive “hard knee” effect.
And finally, they’ve added an Output level for convenient level-matching and a Power switch to audition your results.
“Not only do you get a classic 660-style compressor, but you get built-in 60’s vibe with the “Excitement” controls… your tracks will have instant vintage vibe!” – Michael Vecchio, Founder, Iconic Instruments
