Oh yeah, that Sweep setting is the culprit. It is DEFINITELY not useable that high with Pres and Treb set the way they are. For those that don't know, the Sweep actually sets the "Starting point" of the EQ section (Bass, Mid and Treb all included, not just mids). Set at 0, is mega Dark/Bassy and set at 10 is mega Bright/Trebly. Therefore mega Bright/Trebly + High Treb and Pres = Bleeding ears, possibly forever.
Turn that Sweep to 2 (out of 10) and those settings
may be useable.
@Kev, believe it or not that was the first thing I thought after posting Chris' "head". I thought "someone's gunna post a pic of his head", just didn't know who.
