I haven't used a Tremol-No, but I have similar devices on most of my vibrato-equipped guitars. They work, but they make a noticeable detent at the zero point. It's annoying if you like to do slow, shallow whammy bends. Then again, if that's what you like, you probably don't need one. At any rate, you can try it and remove it if you don't like it.Anyone remember that site where you can order custom neckplates?
Also, i am thinking of getting a tremol-no. Is it easy ito install? Any drawbacks to it?
