I have a Fender Squier P-Bass and am trying to pick up the bass. I have a Fender Rumble 15 and a Crate BT10. Which one should I keep to use with the P-Bass? I know I can listen and decide for myself but I did that already and would like some input from some bass experts. Not planning to gig - just wanna mess with the bass and maybe loop some stuff to play with the guitar. Thoughts?
