I'm considering saving up for my dream guitar. I'm interested in a HSS strat with a Floyd rose trem. What I would also love for my dream guitar to have is a EVH D-Tuna. You can buy this part loose, the EVH company is OK with you adding it to any Floyd rose guitar.
There is some practical requirements. The dtuna needs the Floyd to sit on top of the guitar body and the trem must not recede down into the body of the guitar when you pull up on the Floyd. I don't know enough about Floyd starts to know if this is true for strats by default or if there would be a need for further mods to get the dtuna working?
Then there is also the issue of whether fender custom shop would do this for you? Is there certain things that are just too blasphemous for the custom shop or is it a case of you bring the cash and they will build it. I'm not certain exactly under what paradigm they operate.
