Let us not forget that one J.John Garcia had the Alembic guts taken out of 72-25 (or was it 73-25?) and replaced with Dirt'Marzios, and Wolf seemed to work OK for him. But I myself lean to the philosophy that the cleaner the p/up's natural sound, the better, as one can always add grit & distortion, but one can never take it out.
As to EMGs, doesn't the "M" stand for "metal"? I don't think I've seen anyone but metal folks use them. (In fact, a large part of why I dropped my subscription to Premier Guitar was their penchant for focusing on guys who tour carrying 7 ESPs, identical except for color, all loaded with the same EMGs, and talk about which song they use which one on.........)
Want to put EMGs in your Alembic? It's yours, go ahead. But don't delude yourself into thinking I'd buy it from you.
