I finished up my EVH Kramer (Long story short- I bought a kit and built it) I put a DTuna on the Floyd Rose (Not Original a cheapie Lic Floyd Rose that came with the kit) I have it blocked so it only goes down and suprisingly the guitar holds tune very well- but the DTuna when tuned to d is fine, but when I push it in to go to E it is flat, I fine tune it with the allen screw on the Dtuna and it goes all the way down to the guitar body makinig it impossible to switch back and forth. I am thinking that the Floyd Rose cheapie mite be the culprit. I own an original EVH with the Gotoh and put a Dtuna on that with no problems and I also own a couple Wolfgangs- this is the first problem I have ever had with a Dtuna. Does anyone have any input or suggestions? I greatly appreciate it!
