Tone Settings, EQ, and Mixing Approaches
Phil Collen’s sound design is characterized by a mix-oriented approach that goes beyond merely combining “distortion” and “spatial effects.” Def Leppard has created a “wall” of sound by overdubbing dozens of guitar layers in studio albums, achieving a thick chorus work synchronized with the rest of the instruments. Within this context, Phil’s guitar is meticulously EQ’d to avoid clashing with Rick Allen’s drums and Joe Elliott’s vocals.
Starting with the basic distortion settings, Collen tends to emphasize the mids while cutting the lows and boosting the highs just enough to avoid harshness. This approach is designed for large arenas and stadiums, as excessive low-end can mask the bass and drums, while overly bright highs can overshadow the vocals. Therefore, his EQ typically aims to bring the midrange forward, ensuring it remains audible even when blended with other instruments.
Specifically, when using rack preamps like the Marshall JMP-1, he reportedly sets Treble to 6-7, Middle to 7-8, Bass to 3-4, and keeps Presence at a moderate level. This setup allows for the nuances of picking to shine through while avoiding the compression characteristic of high-gain settings. In modern live performances with the Fractal Axe-Fx III, he prepares presets for each song, fine-tuning EQ and compression according to the song’s style. For instance, “Photograph” features a bright, sharp tone, while “Hysteria” has a synth-like quality with deeper delay effects.
During recording sessions, the unique sound of the ’80s using the Scholz Rockman stands out. The Rockman’s signature compression tightens the midrange, creating a unique sustain that includes harmonics. Layering multiple takes allowed for a sound that approached the expansiveness of synths. Additionally, careful panning adjustments ensured that guitars did not mask each other, directly influencing the production quality.
In the mixing stage, producer Mutt Lange’s meticulous layering and EQ processing played a crucial role. Guitars may sound somewhat thin when isolated, but they function as “ideal thickness” when layered with other instruments. This approach is also reflected in Phil’s live settings, where digital multi-effect presets are adjusted based on the “sound completed by the band.”
Moreover, the use of the Sustainer is a distinctive aspect of his sound design. By activating the Sustainer circuit on the PC-1, he can control feedback during solo sections, achieving a “singing lead tone” that incorporates sustain and harmonics. This adds expressive qualities to his sound that cannot be achieved through EQ alone.
In summary, Phil Collen’s sound design is built on “midrange-focused EQ,” “depth through delay and chorus,” “sustain through the Sustainer,” and “design considering the overall mix.” Simply assembling the gear is not enough; understanding how to position one’s guitar within the overall sound of the band is essential for achieving a truly Def Leppard-like sound.
Affordable Alternatives to Recreate the Tone
Phil Collen’s signature gear, such as the Jackson PC-1 and Fractal Axe-Fx III, tends to be professional-grade and expensive. However, it is entirely possible for beginners and intermediate players to achieve a “Def Leppard-like thick sound” using relatively affordable gear. Here, we will introduce products available for around $100 to $500 that can effectively recreate his tone.
For amp simulators and multi-effects, the Line 6 POD Go and BOSS GT-1000CORE are excellent recommendations. While professional-grade options like the Fractal Axe-Fx may be out of reach, these devices are rich in amp modeling and spatial effects, making it easy to recreate the Def Leppard sound with a chorus and delay combination. Additionally, BOSS’s multi-effects units are intuitive to operate, making them user-friendly for live settings.
If you prefer standalone effects, consider the BOSS DS-1 Distortion or MXR Super Badass Distortion. To replicate the tight, high-gain tone similar to Collen’s DiMarzio Super 3 or X2N, these distortion pedals can serve as the foundation, combined with a compressor and delay for added atmosphere. The BOSS CS-3 is a standard compressor that can help even out the sound while extending sustain.
For spatial effects, the BOSS DD-8 Digital Delay and TC Electronic Flashback 2 Delay are great options. Both support stereo output, ideal for creating the expansive sound characteristic of Def Leppard. Furthermore, pairing these with the BOSS CE-2W Chorus can easily recreate the shimmering tones heard in “Photograph” and “Hysteria.”
While the Jackson PC-1 is the ideal guitar, more budget-friendly options include the Jackson X Series Soloist and Ibanez RG series. Many of these models come equipped with Floyd Rose tremolos, ensuring stability for the whammy techniques essential to Collen’s playing style. Additionally, swapping in DiMarzio pickups can bring you closer to his signature sound.
Lastly, for accessories, consider high-quality parts from Gotoh or Wilkinson as alternatives to the titanium components favored by Phil (like FU-Tone). These can enhance tuning stability and improve the core sound, helping you achieve a consistent tone on stage.
In conclusion, while fully replicating Phil Collen’s sound may be challenging, focusing on a basic setup of “high-gain pedals + compressor + delay + chorus” can get you quite close. Introducing a multi-effects unit can also simplify switching tones for different songs, allowing you to experience the arena rock sound reminiscent of Def Leppard.
