Hi Thinking about buying GK MB200 head and a Markbass cabinet. Particulary fond of Markbass Traveler 102P - 4Ohm. I need an amp that is small, light and powerful so these look like the best options. Does anybody have experience using GK and MB together? I have heard that the speakon cable that comes with GK heads doesn't work well with other cabinet brands. What are your opinions???
