Picked up a really nice SM from 2008 yesterday and have been busy modding it. Added an LED OCD board that came with the game, hooked it up to an external sub, added a red trough light and a red backboard flasher mod that is tied to the pop bumpers so it lights every time the pops are hit.
Also installed an RGB under-cabinet light mod that hooks directly to the flashers so you can choose which color you want tied to an individual flasher. For me, I hooked the red and blue to the sandman flashers and the green to one of the goblin flashers. Totally customizable and takes no longer to install than hooking up an external sub, just a few minutes! The mod will work with all versions of Stern Spider-Man, including the VE.
This kit can also be installed on many other games as I have it installed on my Ironman, Baywatch, LOTR, Metallica, POTC and Funhouse. If you want to hook it to game we don't list it for, please send us a note and we can look into it.
A short video showing the SM mods in action is below.
The under-cabinet light is offered at $60 shipped, the backboard flasher and trough lights, which can be done in red, green, blue, white or purple are offered at $35 and $18.99 shipped, respectively. All are available in my Pinside shop and if you want more than one under-cab kit, let us know and we can provide a discount.
