DO NOT FORGET MIDS.
For 'glass', consider using single-coils (YES, they CAN be quiet, if you know how to fucking use them and treat the space around you!) or humbuckers in parallel. Also, a highpass is important, especially if any bends, double stops, or accidental open string grazes occur for a number of reasons - an often overlooked reason is that if two notes are played at once, and they aren't EXACTLY in tune, there will be a 'beat frequency' down below both notes that is basically an implied note caused by the addition of two waveforms that are not identical... and if you're doing a unison bend, it sounds like a shitty bass drop that should have just been left to die years ago. That, and the fact that soloing on the low strings isn't too common, makes it essential.
Less gain, more compression later if necessary. Scratchy leads suck. Also, mids.
Steve Smyth always gets godly tones, and he said on his board that he likes to put an AT3035 a bit behind the SM57 for solos.
Did I mention mids? Guitarists already scoop too much for rhythm, scooping leads just sounds awful and should be a crime punishable by death.
