EQ And Compression Techniques For Vocals, Acoustic Guitar

This article talks some of the basic Vocal and Acoustic GTR  EQ and Compressor studio recording skills. Even though this is talking about studio recording but still can learn different something from this article

For the vocal Compressor
 He likes to set the hardware compressor’s attack settings at around 30 ms and release settings at about 1 second and my compression ratio to 3:1. Then, he plays with the threshold making sure that at the hottest parts of the vocal, the gain reduction is at a maximum of -3 dB. This leaves me room in the mix to compress further using software compression plug-in.

For the Vocal EQ
If the sound too muddy or boomy vocal –he tends to pull a dB or two at around 200 Hz. This also has the effect of making the vocal cut through a mix better or sound brighter.
He’ll pulls a few dB at around 3 kHz if the sound too piercing or painful. This tends to take the edge off of the vocal without removing any of the clarity.

For the Acoustic GTR
Compare with Vocal, he likes to have a bit more aggressive with attack and release settings than you would with a lead vocal. Medium fast attack (approximately 22 ms) and release (approximately 500 ms) on a hardware compressor with a ratio of 3:1 and then play with the threshold knob until, again, the gain is attenuated by about -3 dB.

For the EQ
Pull 1 or 2 dB at 125 Hz to remove the boominess and adding air or breathe by using shelving EQ that boosts all frequencies above 12.5 kHz. Bringing out the low end in a vocal – add 1 or 2 dB of gain at between 80 Hz and 100 Hz.

Here is my question when I am doing FOH Engineer and the mix sound is perfect but during the artist solo part with some of background music, how could I suddenly change the EQ setting? Should I setup the “Scene and using fade out?” or have other ways can do it?
