hi i'm new to edge pro bridge, been using lo trs for yrs..the problem started when i wanted to change the g string..when i unscrewed the string stopper screw at the bridge, the saddle piece came out together with a spring, then the bridge 'collapsed', now although i placed the spring back in placed and brought the strings back to tension, the height seems wrong cos there's this low string buzz now, and the 4th string saddle is higher than the rest. How do i lock the 4th string saddle back in place flush with the rest? and do i need to adjust the tremolo tension screws cos i wanna leave everything at factory settings..thanks!
