I have a Sunn Coliseum head I use for my stoner metal band. I use a Boss bass overdrive pedal to get the tone I want. I love the way it sounds and I've had no problems with it before, but the annoying red overdrive light is almost always on while I play. Am I pushing the amp too hard? but it isn't even the pedal that triggers it. It also happens when I play without any gain. I am running it through a 400w 8ohm cab, so it's not like I'm even close to getting full power. Should I worry about the light or just keep jamming?
