If you are just starting out you dont need to be swapping your pickups out for humbuckers, just focus on learning and getting it to sound good with what you have.

Then when you have gotten to a better level treat yourself to a new guitar and amp possibly.

Don't buy into all the hype of you need this or need that, blues come's from inside and you can play them on any guitar with 6 strings, getting custom shop pickups or switching to humbuckers, you are still going to sound exactly like you do now, tone is from the fingers. I cannot say that enough, take it from me. I have spent thousand's on modding guitars and getting this and getting that, chasing tone is fun but very exspensive sometimes.
