Firstly, I apologize if this has been asked before, I couldn't find it when searching. I have been using the ampeg scr-di for almost two years for home practicing with the headphone feature and its perfect for that. I was never a huge fan of the scrambler side as I found it too shrill or over the top. But I just noticed recently that the scrambler circuit will not distort like it used to. When I have both the drive and blend dimed there is a slight overdrive but not like the almost fuzz sounds I was used to. It's almost acting like a boost and not an overdrive/distortion. Has anyone had this issue come up or have any suggestions for getting it looked at. I'm almost certain the warranty is up since I've had it for so long and I unfortunately do not have the skill to fix it myself.
