Hi guys Finally I've bought my first gibby and it's rare in my country '86 SG Special. It has a maple neck and rosewood fretboard, and previous owner put a Duncan SH-6 in the bridge. Despite the fact that it plays like butter and i'm totally in love with the look, i'm not completely happy with the tone. I tune in C# standard and play mainly oldschool death metal, so I thought I would get a head crushing tone with this axe. On the one side - clarity for brutal and fast palm muted riffs is okay, but there is unpleasant shrill in the high mids, and powerchords on 5th and 4th strings sound pretty thin comparing to my another guitar (Jackson-style japanese Greco). I tried Duncan Invader SH-8, it has fattened the overall sound, and i guess this unpleasant shrill has gone away, but the problem is that that the top end has gone either, and It cannot be fixed by amp eq (treble and tone knobs on max, and still not enough). Hope you guys can help me and suggest any solutions! (i prefer passice pickups) Maybe SG is not perfect for death metal but i totally don't want to part with it cause it's extremely comfortable to play, and i hate modern metal guitars, and classic models for my purposes like b.c. rich or jackson usually have a floyd rose which i also don't like.
