Hi all ,Ok i have a probably dumb question but i am going to ask anyhow but first a little history behind the question. I am 40 been playing since 11 in all that time i have never owned a guitar with a whammy bar.I recently got a epiphone with a whammy off of ebay ,loved the neck hated the whammy/bridge so replaced it with a tunomatic style. It works great i placed the tunomatic in the right area with some help i got from folks on her but i do have 1 question/problem.The guitar was originally equipped with what is called a locking nut basically the nut has 3 set screws and clamps that hold the strings down i guess???? I have been having probs with the guitar coming out of tune after bending a few strings but HAVE NOT been using the screws and clamps so should i?Or is the lockdown nut something specific with the whammy bar system?
