Yup... Brighter (hence "cleaner/clearer") for sure. I believe the "increased dynamics part" the dude from the video mentions is just the fact that they're bassy-er and hotter as well. That would make the mic pre peak more for sure "when he really digs in".
I really like the tone myself, but I agree with Drew. The fact that they only make them in black nickel kinda makes them hard to fit into most guitars without them looking as stupid as those Dave Mustaine Deans with the mismatched hardware.
Maybe... they would look ok in a blacked-out guitar, hardware and rings.
