This Bass gets its name from its pickup combination. It has one P Bass pickup and one Jazz Bass pickup....thus
P and J(amazing how that just falls into place, isn't it?). This was actually the backup bass for Boss Tweeter,
but it served as a workhorse behind the scenes as Tyler's main bass for practicing. Eventually it was no longer needed
though and was sold so that some lucky bastard could later sell it on Ebay for millions.
