The upside to an undersized bass bar is increased volume and bass response. The downside is increased wolf tones and unevenness. Also, a bass bar that is too weak will lead quickly to collapsing of the top table on the E-string side. Sizing and placing the bass bar just right is a difficult task. Tools I personally use for this task include ruler, protractor, calculator and Ouija board.
