Hey guys, I'm finally almost ready to complete my new rig. I've already got my cab SWR 12 stack 4x12 8ohms 800 watts RMS. My bass will be here later than expected since my parents are "making" me go on vacation till the 29th (gotta wait an extra 10 days). The bass is a Warrior Armed soldier. Now I need a new amp. I have roughly $500 and am looking for a used head. I don't need a whole lot of power but I do need versatility since I play jazz, funk, rock, metal, blues; basically still trying to find myself musically. What are the recommendations here? I've been thinking GK 1001RB, Eden WT 400 or WT500,SWR SM-400s, SWR 350x, Mesa Walkabout. Please help this hard-working high school kid.
