If you buy a Mini-Me I highly recommend that you set your internal jumpers for low gain as the factory setting easily clips. In order to change the jumpers you have to remove the top of the case which is held by two 1/16 hex screws on each end. Then you will have to set four pairs of jumpers by carefully lifting them with tweezers and then resetting them over one prong.
