I did a serach... but the terms are so vague and common it's hard to find anything relevant. I found one post through google that seems to indicate that's what I'm working with on my new RG3120.
When I got it I was actually a little disappointed that I didn't get the same super huge strap pins that came on my other RG's.... The didn't seem quite as safe. But I saw a mention of "Free Lock 2" strap pins or something and I'm wondering if that's what this is?
If that's what this thing is, then how do I find myself the locking gizmo that is supposed to be used with it? I did a quick search at ibanezrules.com and didn't find anything there at first glance. Am I better off just forgetting about it or can you actually find these somewhere?
