Hi everyone I need some help here this thing is driving me nuts. I have a swr sm-900 and a bass pod pro hooked into the effects loop just for some flavor and a 8x10 madison bass cab. I know that the cab is not the greatest in the world but I am saving my pennies for a golliath III 4x10. Anyhow the cabinet is rated for 1600w rms @ 4ohms. The gain is set at 1/3 the way up and the master volume is set at 1/3 the way up and I am using the combination eq 1&2 when I hit the low b on my bass (ohh the bass is a warwick vampire rockbass 5 string) the preamp clips and the output clips and the amp cuts in and out. what am I doing wrong here. Am I a total idiot. If anyone can help please help me or shoot me and take me out of my misery.
