Adam Dutkiewicz

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

Adam Dutkiewicz officially re-joined Caparison Guitars in 2015. Adam 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.

On February 10, 2015, Adam was a contestant on the CBS game show The Price Is Right where he won $51,832 in prizes.

Joel Stroetzel stated about Adam's stage personality saying: "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."

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 2008 shows, he 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", Adam 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.

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.

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.
