I've got the PX5D and it works for Bass. I was just using it today. It works great, has allot of great practice, and jam features as well. In fact it has some Bass specific settings, and features that come with it. I would recommend it. Ive also used the PX4D with a Bass and it also seemed to work out just fine. I would defiantly recommend either of them to you, their great, and power tools.
