Re: The best quality bridge for JS100
Welcome to Jemsite!
I believe your JS100 should have the Edge3. Edge Pro should fit in without any modifications if you don't want keep the existing studs and stud anchors as Edge Pro doesn't have the locking studs either.
If you want to or willing to enlarge the bridge route to allow for the longer fine tuner extensions on FR or Gotoh, I would go with Gotoh as it can be had for quite less than a Floyd Rose Original at least here in the US. Ibanez's Edge/Lo-Pro Edge bridges are manufactured by Gotoh if i remember correctly.
Forgot to add, Schaller also known to be a very good brand and its fine tuner extensions are shorter than OFR, but I doubt it would fit in the Edge Pro opening either. Also, Schaller is the OEM manufacturer for OFR, again, if I remember correctly.
