Re: My brand new JEM7V WH needs a new bridge!!
As having looked at this particular Jem and associated tuning problems, I wish to express my side of the story. Having used and setup Floyd Rose equipped guitars for the past 20 years, I feel that I am perfectly qualified in the field. However, I am always open to new ideas etc, Rich, your tutorial on sharpening the edges is excellent.....something I tried many years ago on a Jackson JT-6 unit but after much messing about with it, failed to improve the situation. I do though, have a flattened Edge Tremolo to experiment once again on in my workshop. I've also tried oiling and replacing studs but to no avail (I will give your Chapstick solution a try though....if it cures the problem, then fantastic).
Fortunately, as a Jackson/Charvel player, when my knife edges wear, I just buy a new Baseplate which are fairly inexpensive....something which frustrates me is that Ibanez will not supply such items. Where I have to disagree with you is that in the past, I have ruined a few of my own knife edges by adjusting the action under full string tension. I have, for many years, removed the tremolo springs, pulled the unit away from the pivot post's before adjusting their height before holding the trem unit horizontal to the body and measuring the action, repeating if need be. In my opinion, this eliminates unneccessary wear....you may disagree but it's just my experience.
Over the years, I have found the top end Ibanez Edges to be great performers (as long as they have not been misused)....I've owned a few myself at one time or another although, my unit of preference has to be an OFR/Schaller FR II due to build quality and feel, not to mention, the ease of getting spares.
Intini, if you are successful with your knife edge sharpening, do you want a part time job!!
