The biggest factor in tone is your amp. Then the effects you use.
You will notice some difference between pickups if you install better ones, but on a 5k axe it isn't worth it unless its playability is excellent, which I doubt.
Wood affects the tone, which you will notice when you can't nail Slash's tones because he played a mahogany guitar. Your strings affect the tone depending on their age and the amount of rust and gunk on them.
Basically a lot of things influence your tone, but the amp is the most important. So don't bother upgrading pups on your guitar. You could possibl look for a better amp, or guitar.
