you answered your own question, pal.
You said the 490/498 combo in the LP studio gave you what you wanted... so why not try that set out on the Epiphone? I've had great success on my Epi Lesters.
you can pick a used set for cheap on ebay
... and re-sell them for what you spent (or more, sometimes)!
Is it really that bright? I was thinking the 59 would better because its less bright than the pgn, am I mistaken? An overly bright neck is something Id like to avoid.
That's a great combo. You may need to throw a A4 or A2 in that pup if you don't like it as it is. 59 is an awesome neck pup. A4 to lessen the bass or A2 to get more mids and round out the highs a bit. Awesome pup!!! Mixed with a C5??? Forget about it!!! AwesomeWell I just ordered the 59 neck and the custom 5 for the bridge. I figure if they are not quite right I'll do a magnet swap, but we'll see.
