Adam Jonathan Dutkiewicz (born April 4, 1977) is an American musician and record producer, best known as the lead guitarist of the metalcore bands Killswitch Engage, Aftershock and Times of Grace, as well as the guitarist and co-lead vocalist for the melodic death metal supergroup Serpentine Dominion.

Dutkiewicz, of Polish, Austrian, Scottish, and English descent, was born and raised in Westhampton, Massachusetts. He attended Hampshire Regional High School. Dutkiewicz also later attended the Berklee College of Music in Boston, studying production, audio engineering, and bass guitar. He graduated with a B.M. in 1999. While at college, he began playing in the band Aftershock with friend Joel Stroetzel. Stroetzel would later join Dutkiewicz, Mike D'Antonio, and Jesse Leach in forming Killswitch Engage. Dutkiewicz was the drummer of Killswitch Engage, until the release of its second album, Alive or Just Breathing, when he moved to guitars, and Tom Gomes became the band's drummer.

He has assumed the role of producer on all of Killswitch Engage's records, except on their second self-titled album Killswitch Engage, which was released June 30, 2009. For this album he took on the job of co-producer alongside Brendan O'Brien (known for his work with AC/DC, The Offspring, Pearl Jam, Rage Against the Machine, Incubus, Mastodon, and Stone Temple Pilots). Adam has also produced for the bands As I Lay Dying, Underøath, The Devil Wears Prada, The Acacia Strain, Unearth, All That Remains, From Autumn to Ashes, Johnny Truant, Parkway Drive, The Agony Scene, Every Time I Die and others. He has been compared to Ross Robinson, producer of many nu metal albums, because of his influence on modern metal and shaping the sound of melodic metalcore. He is also an engineer for Zing Recording Studios, which has produced for numerous artists, including several from Tooth & Nail Records and its heavy metal sub-label Solid State Records.

In 2016, Adam formed Serpentine Dominion also consisting George "Corpsegrinder" Fisher and Shannon Lucas.

Dutkiewicz has been a longtime player of Caparison Guitars mostly using the Caparison PLM-3, a discontinued model, with EMG pickups (EMG 85 in the bridge, and two EMG SA single coils in the middle and neck positions) and DR Tite-Fit .012-.052 strings. He also uses the Caparison Dellinger, Horus, TAT, and Angelus models. He is quoted as saying that he likes the guitars because they have a very "strat-like neck." Ever since 2007, he has been seen using various models and brands, but still uses Caparison for tracking in the studio.

In 2008 shows, Dutkiewicz used a black Parker Fly with an EMG 81/EMG 85 set for pickups. Atop this, he used a custom Caparison, modeled after the Dellinger model. He previously used Parker Guitars for their light weight so as to avoid worsening his back problems, but ended his endorsement due to quality issues after getting his signature model. Sometime in 2008, he switched to using a stock PRS Guitars Custom 22, which he used for a few years. In the video for "In Due Time", Dutkiewicz can be seen using an EVH Wolfgang Hardtail. He has since then switched to EVH Wolfgangs full-time. The modifications done to the Wolfgangs involve removing the neck pickup, pickup selector switch, and tone knob, replacing the Schaller fine-tuning stop-tail piece with a standard stop-tail piece, replacing the locking nut with a standard nut, and installing locking tuners.

In 2015, Dutkiewicz officially re-joined Caparison Guitars. He now also uses Fishman Fluence Modern pickups. He uses his signature model, the Caparison Metal Machine. It is based on the TAT Special FX with Fishman Fluence Killswitch Engage Signature pickup in the bridge position. He left out the neck pickup for more wood mass in the guitar.

Dutkiewicz has used a wide variety of amps throughout his career, including the Mesa Boogie Roadster and Triple Rectifier heads, a Marshall JCM900, a modified Soldano SLO-100, and a Hughes and Kettner TriAmp MKII, which he did not like for metal because he said it "didn't hold together well." He has also used the Framus Cobra and Dragon, the Peavey 5150, the Splawn Nitro, the Diezel VH4, and the Fuchs Viper for distorted tones, and the Fender Twin '65 Reverb and Vox AC30 for clean tones. He is currently endorsed by Laney Amplification, used their Ironheart series of amplifiers and currently using Tony Iommi’s signature amplifier TI-100.

In his current live amp rig, he uses both Laney amps, making use of a Laney Iommi head with a Celestion Vintage 30-loaded Laney Iommi 4x12 cabinet for his distorted tones, and a Laney Lionheart 1x12 combo for clean tones.

For his current live effects rig, he makes use of a Maxon OD808 Overdrive, Maxon AD-9 delay, Maxon CP-9 Pro+ compressor, Boss Corporation NS-2 Noise Suppressor, Boss ABY switcher, Jet City JetDirect DI box, and a Korg DTR2000 tuner. For wireless, he uses an Audio-Technica 5000 Series.

Dutkiewicz currently uses D'Addario EXL115 (.011 - .049) string sets with Intune 1.14mm picks.

Regarding Dutkiewicz's stage personality, Joel Stroetzel stated, "Adam likes to take the piss out of things. Just wants to have a good time—kind of act like an asshole, but in a funny way. He likes to get people going, egg the crowd on. He gets up there and calls the crowd ‘pussies’ and all this stuff. But coming from a guy wearing short shorts and a cape, you gotta take things like that in stride."

Talking about Dutkiewicz's stage attire, Jesse Leach stated, "That's his sort of middle finger to everybody, to all the people who act very tough and think metal has to be doom and gloom and trying to be a cool or tough guy, that's his punk rock way."

Dutkiewicz used to be straight edge.

On February 10, 2015, Dutkiewicz was a contestant on the CBS game show The Price Is Right, where he won $51,832 in prizes, including a 2015 Honda Fit, a 2015 Nissan Frontier, a small trailer, and a trip to Borrego Springs.
