I'm looking for a quality EQ rackmount for my guitar. I know absolutely nothing about rackmounts, so this would be my first one.
(Not any specific number of bands, but definitely more than what's available in the MXR EQ pedal. Just something that will satisfy the control freak in me )
Something along the lines of :

But I have no idea what I should have.

Which models are most ideal for the guitar's frequencies? Anything made specifically for guitar? And if so, which models should I be keeping an eye on?
