+1 on following Tim's advice...and don't forget to check those pots out,esp. the volume pots....if they are 300k instead of 500k(like the ones I have owned), that is going to make a difference when changing pups
What kind of difference do you mean? What pots are usually present in LP Classics?
as noted above in my post, they usually have 300k volume pots-this will make tone warmer and rounder feeling with humbucking pups(which is why they use with the high output ceramic pups that come stock)-only way to know for sure is check with a multimeter(lots of info on web on "how to" )
-if you put in a set of nb's, for instance, with the 300k pots, you may be underwhelmed by the highs ...it will sound different from what you are expecting because the soundclips,vids,advice, are all based on the 'buckers being used with 500k volume /tone pots
I do use 300k in one of my hbucker equipped guitars to take away brightness and I use that axe for a lot of older rock, and it really helps round the highs in a Tim Sult/Clutch sort of way
-this is a variable that can send one on a "wild goose chase" in terms of tone chasin'...happened to me way back in the day with LP's...
