Joel Michael Stroetzel (born July 24, 1980) is best known as the rhythm guitarist from the Massachusetts metalcore band Killswitch Engage. Background Stroetzel attended the Berklee College of Music in Boston but did not graduate. Stroetzel's guitar style is influenced by the bands Slayer, Anthrax, Zakk Wylde, as stated on the World Ablaze DVD. Career While at college, Stroetzel began playing in the band Aftershock. The band broke up in 1999, when Joel formed Killswitch Engage with co-guitarist Adam Dutkiewicz. Joel plays the guitar solo in the track "Holy Diver" and is seen occasionally singing during live renditions of "The End of Heartache". Stroetzel has also performed with the band Times of Grace as a touring musician. Equipment Stroetzel has used a wide variety of guitars and 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.

It has a Caparison Fixed Bridge and through body stringing, with Fishman Fluence Killswitch Engage Signature pickups, a walnut top, mahogany back, and a 5-piece maple and walnut neck. It is the first Caparison guitar to have a pick guard. He also had another signature model which is similar to an Angelus, but with a narrower body and longer horns, somewhat a cross between a TAT Special and an Angelus. 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.
