So, I'm unclear on this and I can't find the answer online. Originally made in 2013 to a number of (up to?) 300, but how many runs were there of the Shanks CC#7? I've read here that the second run wasn't up to par as the original run was, so the original run is what serial #'s? Also, if you own a shanks what did your custombuckers measure? I've read that the neck pu is typical hotter than the bridge on these?
