This is a Focus 6000, appears to be identical to the one in the link you provided. The spacing of the switch holes seems slightly inconsistent. The distance between the first and second switches is 21mm or about .825" measured center-to-center. The distance between the second and third switches is 20mm or about .8" on center. It could be that the holes are slightly bigger than the switch shafts and there was some play when they tightened them down. In any case, smaller than what you are seeking.
You're not thinking about buying the one in the link, are you? Don't pay that much for a Focus 6000. You can have the one in this pic for $300 plus shipping if you want it. The neck is a really nice one, and everything on the guitar is solid and works great.
I don't mean for every post to get hijacked with me trying to sell some shit, I just have stuff available and it would seem dumb for me to sit back and watch people pay more than they need to while buying elsewhere.
