If they haven't taken your money yet, consider yourself lucky. You are in the throes of the G&L option order experience, but because you haven't paid, you still have time to reconsider. There's a bunch of G&L basses that are available on line, used or new, where you won't have to deal with G&L directly. I would suggest you consider them, before things go much further. Once they have your money, the G&L option order experience intensifies. Sometimes it works out, sometimes it doesn't. But they have your money, so there's not much that can be done.
I ordered an option order bass from them. It was probably the worst decision I've made in my entire bass playing career. But I also own 7 other G&L basses, that I bought used. They are great! I'm so happy I have them. But I would never buy option order. Fortunately, I only did that once.
