I just got a new guitar, Ibanez RG 450 with a Edge-Zero2 TREMOLO than i bought the ProLine Ibanez-Style Tremolo Arm w/ Bushing off of musicians friends and can't get it to screw in correctly. Did i make the wrong purchase or am i missing something extremely simple. Sorry if this is a stupid question I've been a drummer and recently moved to japan so decided to pick up guitar since my set is in the states. Thanks for the help.
Also since there i bought the tremolo of a American company(standard) and the guitar is Japanese(metric) could this be the issue.
