Hi All. I did a search, and couldn't find much on this, maybe I just missed it. If I did, my apologies. I'm soon to receive an Acoustic 370 bass head, which will be my backup. That is if the guy I won the e-bay auction from is honest. In the near future I will be buying either a Fender 400 head or something similar. Either Hartke, G-K, etc. or a rack setup, power amp (around 800 watts or so) and pre-amp. What's a good cab that will handle all of these different setups? I'm partial to 15" speakers, I like that warm, deep, old school kinda sound. I'll probably need a 4 ohm cab that can handle at least 400 watts. I only want to haul around one cab. Going by specs alone, so far the one that seems to fit the bill the best is an Ampeg, but it's $1000! Yikes! A bit much. I'd like to keep it under $600.00. I'll be playing a Ric 4003, Schecter 004 active, OLP MM copy (the beater), and Samick active bass, all four stringers. Thanks for any help.
