I must have had good karma because now I am getting a Mesa/Boogie Road Ready 4x10 cab for only $500. I am planning on getting a used Ampeg SVT-4 PRO or some preamp/poweramp thing. I think the Mesa/Boogie is 8 ohms and handles 600 watts. So will 600 watts be enough power to compete with a guitarist that has a Mesa/Boogie 150 watt Triple Rectifier and a sealed back Mesa 4x12? help!
