The DiMarzio DP207 is a high-output bridge humbucker designed for the extended low end and heavy chords that dropped tuning delivers, plus serious treble response for single-note solos and standard tuning. The D Sonic guitar pickup isn't just a one-sound guitar pickup, either. In addition to the standard series humbucking sound, the patented design utilizes 4-conductor wiring to access 2 different single-coil sounds plus parallel humbucking mode, for 3 additional sounds that are distinctive and versatile. Recommended for solidbody guitars, bridge position. Those of you familiar with DiMarzio history will note the visual resemblance to the old MegaDrive, but the design is completely different. Installation direction makes a noticeable difference in the sound, particularly with overdriven amps. With the solid bar toward the bridge, the sound is a little brighter and better-defined, and this is the direction DiMarzio recommends for heavy strings and low tunings. With the adjustable polepieces toward the bridge, the sound is warmer and a touch louder and this works best for standard tuning and more solo-oriented playing. Each coil has a unique tonal character, so the 2 split sounds are different, and parallel humbucking produces a third, clean and bright sound.
