I'm curious. I just bought a used PRS One...not a high-end PRS, sure, but it's great quality for the money--anyway, I'm curious about installing a Kahler Tremolo, but I'd have to buy one first, and I'm just wondering if the posts on my guitar are a standard spacing, or if Kahler even makes/made bridges that would fit it. I just don't want to assume so and find out that I'm wrong, since they run about as much as I paid for the guitar itself.
