Be nice to hear some quality clean to break up sounds or some Vox sounds straight off the bat.
This is what I am always wanting to hear, and what I judge modelers by. Lovers of high gain swear that it is harder to mimic those tones, but I have quickly dismissed some choices based on their anemic or phoned-in clean to light break up tones. It seems to be the place where many just jump past, but it is the foundation for me.
