Description
The LiquiFire DP227 grew out of DiMarzio’s ongoing collaboration with John Petrucci, refined during the tracking of Dream Theater’s Black Clouds and Silver Linings. Petrucci had run Air Norton and custom Ernie Ball variants in the neck slot for years, but wanted something that pushed further in both directions at once: smoother, warmer highs for lyrical overdriven solos, and tighter, more articulate lows so clean chord voicings don’t turn to mud.
Where the Air Norton lineage leans a bit looser on the bottom end, the LiquiFire tightens things up and brightens the low frequencies while rounding off harsh treble edges. The net result is a pickup with a narrower, more focused character rather than a broad wash — it locks in cleanly under heavy gain for sustained, vocal-like leads, then cleans up with genuine note separation when you back off the amp. Petrucci has called it the best live and studio neck tone of his career.
Built with an Alnico 5 magnet and 4-conductor wiring for coil-split or series/parallel wiring options, the LiquiFire is voiced and recommended for the neck position, though it holds up fine in the bridge if that’s the tone you’re chasing.
