I understand why purists dislike meddling with original pins because the vast majority of custom mods, painted cabs, goofy rainbow LED's, etc. just look like ass. It's depressing to see a piece of classic art fall victim to a poorly executed plan.

However, that being said, I'm a huge proponent of upgrades "done in the spirit of the original vision". Color DMD's, mirror blades, stealth LED's, even some custom rethemes improve upon the original formula. Always exciting to see that happen. The creative spirit is what gave us pinball in the first place, yanno?

I like the "God Save The Queen" idea. The key is to make it a short ditty and use a vintage instrument for the sound samples. Or, if you are really serious, install a small xylophone or mariamba to play the notes!
