i received a EVH d tuna today for my axis. i followed the instructions to a tee. when its allt he way out its in perfect D tuning, however when i push it in, the most it will go to is D#, only a half step higher. what is going on here? i have even tried both screws that were included in the set.
Did you try adjusting the small screw in the side of the d-tuna to get it up to E? If you have done that and it wont fit, chances are your fine adjustment screw on teh trem is too low and is preventing the D tuna from fitting under there to make the jump from D to E.

If its not that then im sorry but i cant help you...
