I just landed a bargain on an Ashdown ABM 500 head on ebay ($510, with flight case), and I am ready to get a 4x10 cab pretty soon. So far, I love the sound through house sound systems, but my Eden 210xlt just isn't cutting it on stage. My band plays alt-country-rock, and I'm trying to get more of a dirty growly sound out of my jazz and precision basses. I need a 4-ohm cab to get the most out of my amp. Any ideas on 4x10's?
