I keep my old Squier Strat for sentimental reasons; it was my first electric guitar. As you probably know they are nice but the sound is not the best. I decided to improve its sound buying these Fender Strat pick ups. I have to say that the instructions from the manufacturer are poor (I am sure they can do a better job) and I struggled trying to figure out the connections between knobs and pick ups. I would recommend detaching the original pickguard and use the old electronic as a reference. As you may realize I also bought a new pick guard to assemble the new electronic and after a couple of attempts I was able to nail it down. I plugged it to my amplifier and WOOOOOOOW! What a powerful and beautiful Fender signature sound! For those of you brave enough to get your hands on your old guitar, this is an upgrade that you must do. I am working now on the tuning mechanism and bridge to make it more stable. Just a piece of advice, do not pay attention to your significant other telling you that it would easier to buy a new guitar; this is a lot of fun and you will be rewarded with amazing sound and the satisfaction of improving your beloved guitar.
