What guitar do you have and what kind of bridge?
Post a pic if possible.

It depends on what type of bridge you have, but it sounds to me like you have a strat or similar. You should be able to raise each individual saddle using a very small allen wrench. All you have to do is turn them to the right (tighten) to raise the saddles. There are 2 on each saddle, so raise both to the same height. While you're doing this, play the string to listen for the buzz. Stop raising the saddle *just* when the buzz stops or becomes liveable.

You also may have truss rod problems. If the bridge doesn't fix it, then you should take it to a tech to have the truss rod loosened / tightened.

In some cases you can raise the entire bridge.

Before you start adjusting anything please identify exactly which strings are buzzing and on what frets.

Or, you may need a truss adjustment. I had to do that with my Jackson JK-20 and my Ibanez 12-string, but there's no string buzz or muting, good intonation, and really nice action. And, ditto to the previous posters - we need more info to better assist you.

my guitar is used i got it at a pawn shop for like 140 with the whole setup and it a Johnson i am not sure what the bridge is exactly but it does have whammy bar on it i hope this helps the only frets that are buzzing are the first and second my deep e is the string that's buzzing
