I am in need of a new head. I play in a band with two drummers, each on full kits. It can get pretty loud so I need a louder amp. I am currently playing a GK 400RB into an EV410 and a SWR Big Ben 18". I am partial to SWR and Eden gear, but am unsure what would suit me. What do you guys think would be my best choice of head? We play heavy groove-core style Deftones,Tool type stuff. Any help would be great, I now have my GK head for sale, it just isn't loud enough.
