Re: Jem Help
Hi, the sound you hear is the effect of flutter. You see, tremolo systems like the Edge Pro balance on knife edges, and the design makes tuning stability great when doing trem work such as divebombing and pullups, but then there is little contact between the bridge and the guitar body itself.
The strings and the springs on the back are in a sort of balance with each other. Push on the bar and you shift the balance in favor of the strings, pull on it and you shift it in favor of the springs. The springs at the back are usually "bouncy", so if you hit the strings with enough force, you will cause the springs to "bounce" a little, and combined with the very tiny contact between the bridge and the body, your tremolo and consequently the strings will sympathetically vibrate along with the spring bounce.
It's among the consequences of owning a knife edge-equipped tremolo system, although you could reduce the effect to a certain degree by using something like cotton to stuff the spring cavity with. Hope this helps.
