Hi This is my first post.

I am not able to find anything certain about which tremoloarms will fit a 61 jazzmaster tremolo system. I thought a new AVRI arm would do The trick. But not shure enough to by The trem Unit if i would need to buy a vintage arm also, since they Demand a Way higher Price. So i hoped somebody here, have bought an vintage tremolo system an fit a new arm in it. Hopefully somebody Can guide me in The right direction.

thanks
