What do you do about the battery door? I just bought a plastic ST-122 with a broken door, and Sonic Research was kind enough to send me a new one. But upon putting it on for the first time, I was scared that the little, thin tab was gonna break right then. The battery stays in pretty securely without need for the door, so I've just left it off for the time being. I also have the pedal Turbo Tuner, so I only use it at the house, really. Does anyone have a tip for preventing breakage, maybe a mod or something?
