I'm looking at buying a Gibson SG Junior, with just the one P-90 in the lead position. It's great for distorted tones, but it might be a bit too hot and middy for a good clean tone. Can anyone suggest a way to get better clean tones form this guitar? Do I have to go as far as installing a rhythm pickup, or will equalization do the job?

My ideal clean tone is like an Andy Summers or Kurt Cobain chorus sound. If decent sparkle can be attained without modulation, I'm all for it.
