I turned on my Roadster last night and switched to the clean channel. Everything I played started to break-up way before I wanted it too. I use the Clean setting on Channel 1 and keep both the Master and Gain knobs below 12 o'clock. The gain is usually around 10:30 or 11 and the Master sits between 11:30 and 12. I don't remember getting this break-up before. Maybe I didn't use to turn the amp up as much as I did last night? I thought I had played it before at a much higher volume without getting any break-up at all. Any suggestions on what could be the problem or is suppose to start getting dirty with the settings I have?
