I currently have a SWR LA-15. I am looking to upgrade it so i can get more volume and better sound quality. I am thinking about a Workingman's 15. Question is how much better is it. Yeh, its 100w's more but it has the same size speaker. It cost a lot more so are you just paying for the all the extra electronics or are you really getting a louder and clearer amp. By the way, i play some pretty heavy rock.
