Not sure if anyone else has done this, but I had a problem with my jack coming loose occasionally, particularly when my bass and I travel. I bought a small bottle of blue Loctite (you can get it for under a few bucks at Home Depot, etc.). put a smidgeon of it on the threads where the nut will be tight, it helps tremendously. Same can be said with pots, etc. If any of the blue shows up on the thread where the nut isn't, you can scratch it off lightly with a sewing needle.
Another thing I did to prevent the strap nipples from coming off is take them off, put a small piece of toothpick in the strap hole, and put it back on.
I'm not sure if the large amount of low freqs make a difference, but I know when I hit my low E solidly I can definitely feel the vibration all the way through the neck. Not something I experience on a guitar.
Hope this helps!
