First off, thanks for your response and feedback! , do you mean the entire mix or mainly the guitars lacking high end?
As for the snare, I literally just use the Dominion Transient Designer > EQ > SSL Comp > L2 Limiter.
The snare is 11a and i have one track with just the snare mic and no room going through the above^ chain...and the other with just room and no snare mic going through and EQ > L2 Limiter
