I dinged my Epic once pretty bad and had caught it a few times (including on stage- not too 'cool' looking playing in a squat for half a song). Bought some Dunlops and didn't like them- didn't really trust them either. I'd tried Bob's big washer idea, and that was cool but has some drawbacks with removability.
What I have is a little nylon string through the strap loop that I configured with such a knot that I put the strap on, loop the string around the post, pull tight and presto, like a noose or a lark's head knot.
Anyway just a thought. Please don't yell at me if you try it and it fails. I jump around crazy on stage like the punk-rocker that I am and I haven't lost the bass again yet.
Regards,
Jack
