Before changing the humbucker, hear what it sounds like first. Give us your opinion about what you do and don't like about it and we will proceed from there.

Ok here we go then:
I´ve tried both guitars in the sound booth they have in the store and the difference was quite remarkable.
First the neck felt much better on the sss and sound on the lower notes(bass) came out much cleaner.
but because as i´ve said earlier of my tremolo rage,(lol) and because in the long run it would be less expensive and secure to have already the neck with the LSR Roller nut than carving out the wood in the future.
And" Because of The two Samarium Cobalt Noiseless™ pickups (neck and middle) are wound extra-hot for proper balance with the humbucking pickup." i cant get that classic strat sound i love so much.
So do i have to change the whole set of pickups or can i just change the Hum.?
PS:It still comes with the same case:(

thanks in advance

humm...
maybe i just answered myself...

Per your statement above, you apparently don't like any of the pickups in the guitar now. Premising this, I would change all three to a single coil set along with a new pickguard.

As to what your new three pickup set should be, you will get many valid suggestions here alone.

My suggestion is, if you want a broad range, traditional Strat sound, change to a Fender 57/62 single coil pickup set. This would be your safest alternative as anything else starts to become more of a 'specialty' pickup. Meaning, a 'specialty' pickup will be better at some types of music than others.
