Re: Should I get an electric guitar with single coil pickups or humbucker pickups?
I suggest you to buy Squier Classic Vibe 60's Stratocaster for the music you describe you like to play. later, if you want you can add the singlecoil humbucker version for the bridge
like Lil'59 or Jb Junior. i reccomend you that guitar because i have one, and pickups on it already are amazing

and you will have no issues with pots or anything, just be sure at first, you take it to guitar luthier, to set it up correctly and with better strings. that guitar is amazing electric monster for the price

in about 3 years of playing, that is the only guitar that the stock pickups are allright, no pot issues, no other issues. just must be set up correctly so get her to some good luthier after you buy it

and later, if you want put on the bridge humbucker in the singlecoil version. the only guitar for that money that i didn't find anything to change or swap, tuners ok, tremolo ok, nut ok, pickups great, knobs and pots great !
But as i play a lot of heavy tapping licks it lacks some output for that kind of stuff.. so i think i will add JB Junior or Lil'59 on the bridge and anything else leave the same. but i can guarranty you that the stock pickups are allright for the stuff you're into. it are just fine pickups.
