2 Eq Bands Enough ?

[⚖musicalmemoriesuk]

As mentioned in my Previous post on only being able to boost or cut 2 frequencies in the Tyros4 voice set mode. 

I’m thinking do you really need more as In this case boosting two frequencies made the world of difference. 

Im wondering if using only two frequencies on my Pa700 Will make such a difference in some of its sounds.

You know bouncing ideas from one arranger another is interesting to see what sort of a reaction you get.
