Thank you guys for the responses.
So I've had 4 days with my Ghostbusters Premium now. I thought I would share my thoughts..
Overall this may be the most fun pin I've ever owned. It seems strange for me to admit that because I've always been a Williams/Bally guy. This is my both my first Stern and my first NIB pinball. I'm just really enjoying playing this. One thing I love is that it isn't the easiest game. For me, I enjoy the more challenging pins. They keep me more interested. My 8 year old son agrees with me. He just loves this pin too. He wants to play it a lot. That a plus for me.
The lighting is a 10/10. It's just awesome! The sound clips are entertaining. The variety of shots is fantastic and can be challenging. I love the left ramp being both the subway lock system and the super jackpot shot for example.
Here's what I've already added-
-Stern art blades (look great)
-Stern shaker motor (it really shakes and adds a lot to the game IMO)
-Art's airball deflector (this should be STANDARD from the factory! The airballs were SO BAD)
-Hooked on pinball's Ecto Goggles shield
-Cliff's 7 piece protection kit**
-I also added a small angle bracket in the corner on top of the plastic right above the library. It fits perfect on the screw. This prevents the ball from being stuck in the corner if it jumps up there. I will post a pic.
** I since removed the 2 Cliffy's on the drop targets because I didn't like the ball behavior rolling over them
Adjustments I had to make-
-Bent the switch on the right ramp. It wasn't registering half the time
-Bent the top switch in the 3 ball captive balls above the library. This one was stuck down from the factory.
-Moved the adjustment plate forward on the top of slimer which made him more sensitive to hits
-Slimer hits/drags on the black cover above the right captive ball. If I add washers like others have then he isn't low enough on the far left position making the ball go under him. I called stern and was told that they consider this to be normal and acceptable for slimmer to drag across the black cover. THAT surprised me.
-The auto plunger is too strong as I've said before. I am waiting on a phone call back from stern. I am assuming that they will release an updated game code in the future that will allow for a decrease in the power (like the trough eject). Because of this power the ball doesn't always make it through the top right metal gate.
If the ball is saved and the auto plunger fires (and IF it actually gets past staypuft and through the top right gate) then the ball doesn't pass under the electric gate on the top left. It hits the closed gate and then drops into the PKE lanes. Is this supposed to happen? Or is it supposed to make the top loop around? Stern is supposed to get back to me on this question also.
Once I made the above adjustments and added the needed airball deflector this game has been spectacular. I'm very happy with it.
