Hey guys I had a couple of questions regarding my Recto-verb Combo. I really dig the amp, but event though its a loud 50 watt 1x12 speaker, I need more power to play with my drummer and my band all together. I was wondering if it was worth it down the road to possible get a cab for the amp and stack it (lol). Secondly, for people who know more about the tubes then I do, does anyone think its worth switching the 6L6's for EL34's. And if so, whats the difference? If both of these questions could be answered I would much appreciate it.
