will this make a big enough difference?

I have an epiphone fat-210 black not a very expensive guitar at all. I was wondering if a really good bridge pickup put into it will make a dramatic diffrence from it's at the moment characterless and tonless sound ,im pretty sure it wouldn't be worth it but i decided to ask those who maybe would know thanks
oh yeah the rest of my equipment is good so it's not that.

[font=trebuchet ms]What does it sound like unplugged, on it's own, without an amp?

Even a great pickup can only work with what the guitar starts out with. A guitar that doesn't sound good on it's own will just get louder when you plug it in. If it has a good sound, the right pickup can bring that out for you.[/font]
