My only two basses are a CIJ Jaguar and a Squier P-Bass. I recently put them neck to neck and they are the exact same thickness. Could it be that the P-Bass neck was shaved down a little too much in the factory? I know basses have slight variations and have even heard of a P-Bass neck that is thinner than normal. And what it the difference again? Its from 1.75in to 1.5in, P to J?
