Hi folks, I am currently considering changing my amp over from a Mesa 400+ to a combination of an SWR interstellar overdrive and a smartlight SLl600. What I am wondering is whether this system will give me enough versatility and enough power. I was disappointed with my 400+ with the amount of grind. I am wondering whether the SWR will give me that valve feeling.ie warm and big followed by nasty and gritty when I dig in? My cab is a Mesa 1516be. I can't remember what the power handling of this cab is and whether I can bridge the smartlight into 8ohms and have the cab take it ok?
