There appears to be no tilting of the biscuit like the original design, but couldn't you accomplish the same thing by setting it up square in the first place by way of the main mounting bolt? I would think that there would be plenty of range to swing an arc around the mounting bolt until it's square to the string and then use the vertical adjustment for your tuning. That seems simpler than the old biscuit that had a bunch of "by guess and by golly" when trying to set elevation and tilt.
