What this be a stupid idea? I'm wondering if it still might give me a nice Eric Jonson or some other strat player's sound. The pick up set up on this guitar is HB, Single, HB.
If not, are there any humbuckers that can be versatile enough for a rock n' roll sound and blues/jazz sound that could be put into an Ibanez RG2570?

I'm not sure how it would go down but seems like an interesting idea!

Yea, you could put a Fender single into an Ibanez. But, i think anyway, if u wanted blues/jazz and rock, you might have to replace both humbuckers.
