Description
Warren DeMartini didn’t just shred through Ratt’s 1980s radio takeover — he wrote riffs and solos that made other guitarists rethink their approach entirely. “Round and Round” and “Lay It Down” weren’t just hits, they were technical benchmarks, and the pickup behind that tone finally has a name: the RTM, short for “Rattus Tonius Maximus.”
This is a high-output bridge humbucker loaded with an Alnico 2 magnet, a deliberate choice that keeps the aggression from tipping into harshness. Alnico 2 gives you a softer compression curve than the more common Alnico 5, so power chords stay articulate instead of turning into mush, and single-note runs retain their pick attack even when you’re pushing a hot amp into saturation. It’s tuned to sit right where DeMartini’s playing lives — dense chord voicings that need to stay defined, and fast, precise leads that need to cut without becoming brittle.
This particular listing is the Trembucker version, meaning it’s wound with wider pole spacing to line up correctly under the strings on guitars with tremolo-routed, wide-spaced bridges. Get the spacing wrong and you’ll have poles missing strings entirely — this one’s built to sit right.
Finished in reverse zebra (black bobbin toward the neck, zebra-striped bobbin toward the bridge), it looks as sharp as it sounds.
