No just plain wrong. If one wanted to roll off the treble ever so slightly then there are better tools for that, such as tone controls, an EQ or more room treatments etc.
Who said anything about tone control or rolled off treble? Please re-read my my findings. But I suppose I could go back to the 'right' configuration, satisfied that I'm not doing something I'm not supposed to be doing, and just pretend that it sounded better than the 'wrong' way.
Scream 'cables should be (insert word here)!' all you want, Shardorne. As Elizabeth said, "Theory is great for arguing." I'm not here to argue.
