Here is what I have: GK 400RB head SWR Big Bertha 18" cab EV 410 cab The problem is the head can hardly power the cabs enough for me to hear them above my band. I want a modern sounding head with plenty of headroom. I have tried some things out at the local Mars music but am unsure of what to get with my cab setup. I play fingerstyle and want enough volume and power to be able to use my fingers lightly without having to really play hard to be heard. My band is a Deftones,Soulfly,Jane's Addiction style groove-core thing, so I am looking for that kind of sound. What do you guys think would be the best head for me with these cabs? The current setup sounds muddy and undefined, not much in the way of balls. I usually have to kick in my Boss Overdrive just to be heard. Any advice would be appreciated.
