For ease of swapping, the following Floyd Rose Tremolo Systems share the same dimensions and can be swapped with each other without the need for additional routing:
***The string lock screws of the Floyd Rose Special are marginally shorter than on the Floyd Rose Original. If your guitar was routed using the Original routing diagrams, this will not be an issue-- some manufacturers, such as Fender, route smaller, tighter cavities on guitars outfitted with FR Specials, in which case you may have to route a little more space if you want your tremolo to have upward motion.
Note: After removing studs and inserts from a guitar body, the postholes may be stripped (the new studs and inserts may not fit firmly in the hole). If this occurs, you'll have to dowel the holes and redrill for the new studs.
Licensed Tremolo Systems
There are dozens of "licensed" tremolo systems on the market, each with their own dimensions, specs, and materials. It should be noted that many of these may require additional modifications to the body cavity to allow for the patented Floyd Rose base plate shape and size. If you are unsure, please check out the routing diagrams available on the Technical Documents page.
