I just picked up a 65 American Vintage Jaguar. A bit of an impulse buy as it was different and on sale. I was intrigued by the mute plate and did some research to find out what it was. However when engaged, my mute plate does not mute the strings equally. It barely touches the bass strings and presses too hard on the high strings. It's basically useless, the guitar sounds like garbage with it engaged. Can this be adjusted to nicely mute all strings to the desired level?
