The A-Bomb is similar to a Rebel Yell in some respects but it is also hairy, gnarly, and ill tempered. It's a thicker and bassier pickup with more of a 'cut' in the highs but with less of that brilliant harmonic sheen that the Rebel Yell has. The result is that it is darker. What about a C-Bomb for metal?
Has anyone tried a Painkiller in a LP? What about an Aftermath? Somehow, I wonder if an Afternath would fit the bill?
Boosted RY bridge pickup with heavier strings sounds killer though, just throwing that out there.
What amp are you using?
