I have Hipshot Detuners on two basses - an American Elite P and an older Stingray (pre-special). Neither can rest safely on my Hercules wall hangers unless I put them on backwards (i.e. with the front facing the wall). I hated that look. My solution was to install String Swings - which allow more space for the lever and larger tuner to not be resting on the actual hanger. I have to leave the Detuner in its Drop D setting otherwise the lever rests on the hanger.
So my solution - String Swings and Drop D.
