Here is my Bluesbreaker clone. I got it all put together today also. This is a nice low gain OD pedal. I think it has less gain than a Tubescreamer, and don't have the mid boost of a Tubescreamer. I would say it is kind of flat, but maybe has some extra crunch in the highs. Pretty fat and chunky boosting something else that is high gain, like a Boss BD-2 or similar would. Kind of reminds me of a low gain Rat or BD-2 type pedal. I know the Bluesbreaker, Guv'nor, and Shredmaster were all kind of in the same family, with each adding more gain and EQ.
