In an old thread in the "tele forum" (I think), was a very nice clip of a very close approximation of the "bluesey dumble lead tone" from a mark 5-25. I'm unable to duplicate it on the larger Mark5-90! If I remember correctly, Both treble and bass on 0 (!) and mids noon to 1, gain below noon. Then to a very unusual 5 band EQ setting which I can't remember (LOL) All on Extreme channel . Anyone have any suggestions? The strategy was "interaction between mid settings and mid slider in 5 band EQ.
