I'm playing in a death metal band, and I'm tuning my bass F#-B-F#-B-E, and I've got a 4x10 EBS cab in my sights, but I'm not sure that it can deliver the low F# punchy enough. Also, since I'm using heavy distortion and I want to achieve that really mean, "tractor" sound, I'm not sure what head i should be using. I don't want to fiddle around with pedals anymore, and I want a good blend of the fat low end and the really mean distortion. If anyone has any ideas for me, I would appreciate it.
