I have an idea of what you mean and am a fan. My LP Junior and BFG both definitely have that meanness and grind that stands out. The dogear JR a bit more than the soapbars. I only have one guitar with a filtertron and it's kind of weak, so can't really comment to that. That said; pretty sure neither are going to end up in this guitar. My current favorite is probably a Nazgul, a bit similar in that aggressive and raw tone to the P90 and nice and quiet when you want it to be. That's not to say I'm comparing the two, just reminds me of that in your face chainsaw vibe.
