Hey, i've lurked around this site for quite sometime, and just today decided to register. I seriously think i read this site more at my office than doing any actual work. I've played bass in various hard rock bands since i was 13, and never really had any amp problems untill now. Keep in mind i have very little knowledge of ohms, or wattage. Untill not to long ago i had a Peavey Sessionbass head and a Peavey 412 cab. Sounded great, but saddly it was stolen. After a long year of trying to rebuild my rig i had a bunch of random used gear. I traded it all in last week and for about 200$ difference got a brand new Hartke vx810 cab, rated at 4ohms/800 watts. I also have a brand new Hartke 3500 head. So my question is, is there no hope for the 3500 head efficiently pushing this cab? Do i ditch it in favor of a different more powerful head? Or do i use it alongside a poweramp?
