The original Prusacaster had an issue where the mounting holes for the bridge and neck were uneven when compared to each other and the body of the guitar. This version fixes the holes so the strings sit evenly on the neck. I also removed the middle hole on the neck mounting area as I don't think it served any purpose.
DISCLAIMER: I have yet to test this model so I cannot confirm this will work as expected. I will update when I have a chance to build it.
The author remixed this model.
