Quoted from davids1024:One of my first mods when I receive my Metallica Premium will be adding a shaker motor. I see that Stern and a lot of third parties sell them. Are they all the same or are some better than others?
This may seem like a newbie question but what is exactly is a shaker motor for? I mean I figure that it is supposed to shake a specific toy on the playfield like Sparky in Metallica but doesn't the machine do that already anyways being stock? Or do you have to actually purchase and install a shaker motor to get the Sparky toy to shake and if you don't then it doesn't shake when the mode is activated because it doesn't come with a stock shaker motor?
