I have to confess here I am the new owner of this ACDC  The reason I asked Brett if it had a shaker motor was that I thought that he may have asked the seller and had the inside info.
I bid on this machine on a whim at the last second and had a maximum bid of $4050 which ended up being the winning bid. I figured I would go $4050 in case someone else went $4000 and I didn't wanna miss out by a lousy $50 and end up shitty for a week...turns out I was right ...sorry Brett blame your son.
Truth is this is not a title I have ever really considered buying but I have been cashed up for a while and after just missing out on a few machines lately I figured I'd go for it and if I get for the right price didn't matter if I didn't like it I can easily move it on without taking to too much of a hit.
Arrived today....no shaker and no code updates since new. On the plus side this machine is mint looks and even smells brand new. I spent half an hour looking for anything to fault. All I could come up with were some finger smears on the glass, some light ball drag marks here and there on the play field and some ball drag marks on the acdc targets, all of which came straight off with a quick clean and polish. Plays snappy and has a new feel. I have only had 4 games so far in 4 different song modes and high scored on each, not that I played well more that it was a sited pin and no one any good ever played it.
Now all I got to do is go and play and learn the rules and see how I like it. Will keep you informed on what I think of the game as I get to know it.
