Not a noob to bass playing, but I've been playing out of the same 350 combo for the past 10+ years and have done little to no research on gear in that time. But, I finally wanted to upgrade, so I got the Mark Bass Little Mark Tube 800. I was just wondering if anyone else here has one who could give me a quick rundown on the controls. It came new out of the box with no description whatsoever. Any help is much appreciated.
