Guild called me today. They acknowledge they mistakenly installed a rosewood bridge on this guitar. They don't know how it happened, precisely, but they admit the fault is theirs.
They offered to take the guitar back and install the correct ebony bridge. I told them I'd think about that, and they said to take all the time I want.
On the one hand, as has been pointed out here, the guitar sounds really good the way it is, and my experience says if it ain't broke, don't fix it.
On the other hand, let's say someday I decide to sell it, and I wind up in this conversation:
"Well, this guitar isn't original. The bridge has been replaced."
"Oh, no, that was how it was built. Guild mistakenly put a rosewood bridge on this one."
"Yeah, sure, buddy."
In the meantime they're replacing the bridge pins and saddle. I asked if they could also document in writing that this guitar was built this way. That could turn the issue from a liability into an asset; it's unique, a one-off from the factory.
So I have options.
Now I wonder if they didn't realize the mistake before the guitar left the factory, and stained the rosewood darker instead of replacing the bridge. That would account for the pins and saddle turning colors.
