Lately, though when my A and E strings are in tune, the tuner pegs sit parallel with the headstock. When I flick the detuner, they touch.
Loosen the A string all the way off the machine, turn the tuning machine a little bit, and rewrap the A. That should put it so when the A is in tune its ear won't be in place to get bumped by the E's machine when you drop it down.
That's the problem I had on my Hammer Cruise bass, and it's a quick fix.
