i've been wondering this. i used to know the answer, but it faded from my mind. that thing on an some electric guitars, it's like a stick and can go 360 degrees. what is it and what it is supposed to do? would you say it's better or not worth having?

I have no idea what you are talking about, the only thing I can think of that is vaguely stick like and can go 360 degrees is a trem arm

yeah, i think that's it, what does it do?

A tremolo allows you to alter the pitch of a note or chord

oOo, that's kinda cool, thanks telefreak
