Ok, so i decided to put some heavier strings on my strat i just got for christmas. I used to have normal regular gauge strings on it but when i tried to put the new 11s on and tried to tune the guitar the bridge started pulling forward way to much. It also will never stay in tune for even a second. Do i need to adjust something with the bridge or is something else wrong? Thanks for the help.
I just got new strings to downtune, so i got 11's. I would say that yours are too tight and you need to losen them, but i really wouldn't know.
Your tremolo is set for 9's. If you want to use heavier strings you will have to tighten the spring claw in the back of the guitar and maybe add a spring.
You're bridge just needs to be adjusted for 11's. Right now it's set up for 10's. (or whatever gauge you used before)
Going heavier gauge requires having your guitar setup for it. Nothing major. If you can do it go for it. If you can afford it have it set up professionally.
