I've got a babicz, a badass, a schaller, and a stock L plate, all on jazz basses and I can't tell enough difference in tone/sound to say which one is better in that respect. For playability however, the machined locking bridges are my favorites. Short of any other way to describe it, the strings feel more planted?
