Since they are a lower gain tube, will that result in a cleaner tone as the channel volume gets turned up? I love my Sixty-Five, but it hates my SG Special's P90's. The pickups are loud as hell, and I can't seem to get it to sound clean above about 2 on the channel volume. What do you guys think?   Mike Kaus (mm210) Username: mm210 Registered: 05-2006 Posted on Wednesday, September 29, 2010 - 04:48 pm:    It really shouldn't do anything in that circuit. It's only used as a PI, not a gain stage.
