Makes sense. I checked the measurements on another bass I made with the same 30.25" scale and the G is right at 30.25" and the E is at 30.50" with the A and D in between. Fortunately, there's almost 1 inch of travel for the saddles on the Guild bridge. So, making sure I have adjustment room beyond 30.25" is the way to go, right?
I need to rethink this. That's what I would do in most cases,
but maybe not in this case, because the bridge saddle positions are already staggered, like compensation. You might wind up with the larger strings too far back even when the saddles are farthest forward. I'm not sure, since I haven't had a Guild for almost 10 years and I can't tell from your bridge photo how far the positions are staggered. Looks like maybe there's about 3/8" stagger from one side to other.
Sorry, I shouldn't have opened my mouth before considering that you weren't talking about a bridge where the saddles can all travel to the same point.
