Just picked up a Herbert mkii loaded with JJ KT77's and JJ 12ax7's in the preamp. Channel two sounds like it's lacking attack and girth, channel three has a loose low end while palm muting. The note return is sluggish and fuzzy. I'm playing through a Mesa 4x12 traditional cab. In comparison, my EVH 5150iii has more attack and tighter more brutal bottom end while palm muting. My first guess is that it needs new tubes in the preamp since v1 is microphonic. There might be others that are bad too. The guy I bought it from (online sale, bought used, so I never heard it prior) said it was fine and the tubes are only 3 months old. Also when on channel three, if I drop guitar volume and increase master volume on the amp, a terrible high pitch ring/oscillation ensues.
Would bad preamp tubes cause the Herbert to react this way - aside from the microphonics...loose bottom end, lack luster attack, etc?
Please help!
