A bass player must have!!!!!

Everything you need for practice and reference. I have a lot of different apps for bass guitar and this is by far the best one out there. So much information and so easy to use. Any musician could benefit from this but especially catered for Bass. I belief they also have apps for guitar,keys,uke ect. GET IT!!!!!!!
