deleting useless threads, this was the case a few years ago, anything and everything was deleted.
a buzz stop is a seperate peice that screws onto the trem unit. it requires NO modification at all, and increases the break angle over the bridge, thus increasing the string tension and stopping the string jump issue.
every now and again(depending on playing style) its good to have a mustang bridge and a buzz stop.
and in reality, you may want to try a mustang bridge first.
the cost would be the same and you won't have to take it to a tech. If you find you are having string jumping problems you may want to invest in a buzz stop but you should be alright.
