Hi guys, I am having issues setting up my FR to maintain drop D tuning when I use the whammy bar. It's a Floyd Rose "Pro" bridge currently set up to fully float and the guitar has a behind-the-bridge rout. All the strings have been well stretched and played in by now. What I'm trying to do is set it up in drop-D with enough play in the fine tuner to bring it up to normal tuning for those songs that require it. The thing is that after tuning (which remains quite stable with gentle vibrato) as soon as I use a divebomb the low D comes back up a whole tone to an E! I just spent 5 full minutes continually re-stretching the string and retuning to D but every single time the pitch comes back to E. What gives? I just don't understand this. Hope someone can shed some light on it. Thanks in advance.
