Compressor tips

Compressor Tips

Try putting the compressor as the the first block in the chain. Compression works better on clean tones than high-gain tones. The following settings are some very basic starting points to achieve some specific sounds.

Ringy

THRSH: -17.8dB

RATIO: 10:1

ATT: 150ms

REL: 987ms

This setting is heavily compressed, making chords and single notes thick and even, and sustain like, forever. The medium attack allows the guitar strings to ring, and the long release holds on to produce a massive, Neil Young-like sustain.

Chunky

THRSH: -15.5dB

RATIO: 5.1

ATT: 11ms

REL: 102ms

This is the fat, ballsy sound that drives many of the guitar-heavy bands of the late ’70s and early ’80s. It’s mildly compressed with a fast attack and a medium release, which allows all the strings - from low to high - to sound evenly for a massive punch. Think "Barracuda" by Heart.

Chicken Pickin’

THRSH: -31.4dB

RATIO: 6:1

ATT: 1ms

REL: 25ms

Play this sucker on a Telecaster and ride it all the way to Nashville. The fast attack nails the initial string impact, and the fast release lets it go pronto to minimize sustain. The result is a clean, snappy pluck that works great for those blazing cowboy cascades.

Smooth

THRSH: -27.5dB

RATIO: 10:1

ATT: 50ms

REL: 38ms

This setting is squashed pretty hard with a high threshold that pretty much grabs the entire signal to produce a sound with no sharp edges. The resultant velvety texture is wonderful for smooth jazz tracks and other sophisticated guitar tones.

Dramatic

THRSH: -30dB

RATIO: 7:1

ATT: 250ms

REL: 250ms

Clean notes that float in languid, ethereal sustain - think Ry Cooder’s brilliantly sparse lines on the Thelma & Louise soundtrack - are provided here. The slow attack allows the note attack to retain punch and impact, and the long release keeps the sound ringing. This expansive and evocative setting works great for slide parts, as well.

Funky

THRSH: -21.6dB

RATIO: 7:1

ATT: 61ms

REL: 84ms

To accentuate those funky, biting pick attacks - as heard on classic Sly Stone and Earth, Wind & Fire tracks - this medium attack and fast release does the trick.

The Axe-fx use from 1-10 rather than ms for the attach and release settings. They are scaled in an inverse log relationship to 1 to 1000ms. This was confusing at first because a setting of 10 indicates a faster attack rate which means 1 millisecond. Same thing with release - just remember they are rates and not times. Faster rates mean lower values.

Axe-Fx Setting : Actual Time (attack or release)

1 : 1000ms

2 : 954ms

3 : 903ms

5 : 778ms

7 : 602ms

8 : 477ms

I tend to stay the 9.X range for most things:

9.0 : 301ms

9.2 : 255ms

9.5 : 176ms

9.7 : 114ms

9.9 : 41ms

9.92 : 33ms

9.95 : 21ms

9.97 : 13ms

9.98 : 9ms

9.99 : 4ms

10.0 : 1ms
