Ande, are you playing with the volume turned right up? If so, back it off to about 4 or 5 and compensate for the volume change on the amp.
If you balance the volumes (guitar/amp) to the point where any more volume on the guitar will cause distortion, you can play clean and bring in distortion by upping the guitar volume knob. As you're already on the cusp of clipping the sound, turning up the guitar will not get anymore volume, you'll just get more distortion.
