Recently the tremolo on my Squier Classic Vibe 50′s strat broke, so having already done some not insubstantial modding, I decided installing a Floyd Rose tremolo would be an easy task.
Having removed the stock bridge, comparing the size and weight made me realise how much extra work it was going to be than I expected, but I decided to forge ahead anyway.
After removing the bridge, the first step is clearing a gap in the pickguard large enough to accommodate the mounting pins. This is fairly easily accomplished with a sander and chisel.
Once this is done, the extra holes to mount the pins must be drilled, and the pins installed. The hole for the inertia bar may need to be expanded somewhat.
With the work at this end accomplished, the locking nut now needs to be installed at the headstock. Again, with a simple sander and file, it was fairly easy to achieve a smooth, flat mount.
The new nut then simply screws in.
The Floyd Rose tremolo is much taller than the original Squier tremolo, so if you are mounting it on top rather than routing a hole in the body, you will need to do something to avoid unplayable action. I decided to try using a neck shim made from fiberboard. This still leaves quite a high action, but will do until I decide to take everything apart again and sink the bridge, a neater option.
