My Marshall 4100 has a distinctive fuzziness in the line out signal. It sounds nothing like the speakers do (ok so it's not a speaker ).

You would have thought they would have made this less fuzzy and more chunky.

My friend's Mesa Boogie F50 sounds remarkably similar using line out or speaker.

Any comments as to why the fuzziness and the obvious difference in sound? Why such a bad job after manufacturing amps for so long. Maybe it was their first attempt at line out.....not sure.....
