Hi, I was wondering what would be a good cheap head for the carvin RL410T that i'm thinking about buying. by cheap i mean like 350 or less (perferably). the cab is an 8 ohm cab and rated at 800 watts. i'm thinking that i would need at least 250 watts if not 300 watts. have any of you found the cab to be power hungry? i'm opened to used products also.
