COCOB: You use the typical "bathtub-settings". That means: much bass, little mids, much treble. These settings work very good when you play alone, but in the band-context, the guitar goes down. The first step has to be: Add more mids! The guitar is a mid-instrument. The best sound when you play alone is never the best sound in the band-context.
From there on, be careful with your presence control (if you have one at your amp). Try to take away some gain too. Less gain=more punch. I know that you have gain on 7, but keep in mind that randall has very much gain and that the EMG has so much output. The gain of my powerball is always between 4-6/10 when I play with a band.
You have to tweak during the rehearsals, because your amp sounds different
a. in bandcontext
b. at high volume
