Compressing guitar in the mix
For acoustic and clean electric guitars, I use Sony wave hammer Guitar presets. The compression settings are:
Ratio: 5.0 is to 1
Attack time: 15ms
Release time: 15ms
The threshold is lower in volume compared to the vocals, the primary reason is that guitars need to sound a bit lower than vocals in the mix or else it will dominate the vocals. Compressing at -20dB ensures that any strong level above it will be suppressed five times to control the volume and not being too loud. Guitar sounds are not sharp transients in nature unlike vocals, kick and snare. It will have a sustaining and delaying sound. So a medium set attack and release time is good.
In addition, this article illustrates some compression techniques on guitar solo.
Compressing bass guitar the mix
Bass guitar sounds needs to be compressed to provide a steady beat backbone to the song. This is very important in modern rock and pop tracks. And because of this, I use Sony wave hammer Bass guitar presets with the following settings:
Ratio: 6 is to 1
Attack time: 40ms
Release time: 80ms
The main concept of creating a big bass sound is slow attack and fast release. This is because since bass are not super fast transient it needs to develop it’s level first then set compressor to attack the signal and release it immediately, the effect is a loud sounding bass. Compression settings is a bit higher than guitar and vocals, because bass needs to be more uniform in sound to provide a steady beat. You can also read this additional resource.
Compressing kick drum in the mix
I do not compress kick drum in the mix because I want to sound real, alive and not compressed. Compressing kick drums in my experience, takes away its deep bass sound so I do not like idea of compressing it.

Compressing snare drums
Snare drums needs compression, so to compress snare I use these settings :
Compression ratio: 5:1
Snare needs to sound natural even though it is sharp transient in nature I prefer to compress snare with a slower attack time and faster release. This will give a full snare and powerful sound. Compressing with too fast attack time can flatten a sound and will make to sound dull.
