Alright, so I bought a used Ibanez Ergodyne EDB605 bass and the action is too high for my liking - it's impossible to tap with. Just now noticing though, I'm missing a small screw for the E-String on the bridge! It's kind of a noob question, but will not having this screw affect the adjusting of the action that I need to get done? Do I really need to call up Ibanez to order a 20 dollar screw?!

So, Here's a picture. You can see that 1 screw is gone. What should I do? :|
