Re: Want my Epi SG to brighten up!
First of all, you need to change out the pots and caps.
500k CTS pots and .022mfd caps should brighten it up some. As far as which pickups to use in it, that depends on how the guitar sounds unplugged.
For a bright sounding guitar, I would suggest a pair of Pearly Gates in the neck and middle and a Custom or a Custom Custom in the bridge.
For a thicker sounding axe, or if you need less mids, a pair of 59's or Jazz's in the neck and middle with a Custom 5 would work well.
For a more vintage, early 60's/late 50's type tones, a set of Seth Lover pickups would work great.
