EQ SETTINGS FOR MICROPHONE ON KEYBOARD

[DIANADIANA]

I have the psrsx700, but i don't find never satisfactory eq settings for my microphone
Sometimes i have a custom eq for the general settings, but i can also disable if is necessary. Any advice for custom the mic eq? I want have a good sound without many whistles, rustles and noise, if is possible.
My mic is the shure beta 58
