Is it worth replacing them with some better quality ones? I've never done anything with pick ups before, but i'm a real tone freak and i'm starting to recognise crappy sounds and i'm constantly trying to fix them.

thanks people

I have had a few ibanez's and the pickups really varied with each guitar, with my ICX120 it was alright, but could use a replacement. On my RG2020 it had the V7 and V8 and they sounded great. and on my current one i only have a stock neck humbucker (bridge is a JB) and it sounds pretty good for a fat clean sound.
