I think I'm ruined. I took my Klon tonight and did a side by side with my AC Booster. The Klon sounded sooooo good! I had the drive on 1:00 treble about 11:00-11:30 and the volume at 9:00, just a tad above unity. Man that things sounds smooth and thick then I stepped on the AC Booster (up till tonight I was really happy with it) it was raspy and sounded like, well, a pedal. Like I said, I think I'm ruined.
