I want to buy a solid state amp to save some wear and tear on my tube amp (A Mission 5e3.) I'm debating between the 5 watt Street Cube and the 50 watt EX. I've read that that 5 watt feels quite loud and has a cabinet made of MDF board and feels sturdier than the 50 watt EX. Some say that the 50 watt EX sounds "tubby" because the cab is made of plastic. I'm probably never going to busk, but would like to practice singing into a mic while playing either acoustic or electric in my basement and family room. I know there are other Cubes (like the 40GX or 80GX-- which both have tweed channels) but I think two speakers would be cool for the stereo jazz chorus sound and I like that you can use XLR mic inputs. Thoughts on whether I should get the 5 watt or the 50 watt EX?
