Willem Rebergen is a Dutch record producer and DJ who uses the stage name Headhunterz. He kicked off his career in 2005, working on the hardstyle subgenre.
He developed an interest in music at an early age. He joined a children’s choir with whom he recorded Christmas albums. This gave him early exposure to a professional recording environment.
His first exposure to hardstyle music was in 2003 when he attended the Qlimax event. The event propelled him to work on becoming a hardstyle musician. He purchased some DJ equipment and started making music on his computer using the FL Studio software.
Initially, Rebergen joined with Bobby van Putten to form a group called Nasty D-Tuners. The friends were signed to the Hardcontrol record label but left the label due to frustration. They signed to Scantraxx, but they were forced to change the name of the group to Headhunterz due to a disagreement with their former label.
In 2006 he released Aiming for Your Brain/Left Some Answers under the Scantraxx label. Bobby van Putten left the group later that year to concentrate on his studies, thereby leaving Rebergen to carry on the Headhunterz name.
Following the split, Rebergen released several tracks in 2007. Scantraxx then gave Headhunterz a sub-label called Scantraxx Reloaded for him to administer.
He formed a group dubbed Project One with fellow Wildstylez. They worked on a 13 track album titled Headhunterz & Wildstylez Present: Project One which was released in 2008.
In 2009 Headhunterz released new singles. He created the song Scrap Attack, which was used as the 2009 Defqon. 1 Anthem. The year 2010 was pivotal for him as that was the year his international bookings outnumbered his national ones.
He released his album Sacrifice in March 2012. He signed with Ultra Music in 2013 and released his first single on the label on 30 August on that year. The song, titled Colors, hit the Dutch iTunes charts. Headhunterz launched his label called HARDwithSTYLE Records with Ultra.
He has performed at festivals such as Ultra Music Festival and Tomorrowland.
Headhunterz loves working with hardware more than many of his contemporaries when composing tracks. He uses various keyboards including a Moog Little Phatty Stage II, Access Virus TI, Minimoog Voyager XL, Alesis A6 Andromeda, and Roland A-500 Pro.
Hardware effects units like the Manley Massive Passive stereo tube EQ, UA 1176LN limiting amplifier and Empirical Labs EL8 Distressor are part of his arsenal.
An Apogee Duet 2 audio interface handles some of the input and output duties in his lab.
He’s not a total gear-head though. He uses various software effects processors such as Ohm Force Ohmicide, FabFilter Pro-Q, ValhallaRoom reverb, Sugar Bytes Effectrix as well as iZotope Stutter Edit.
Headhunterz runs his setup on the macOS platform. Over the years he’s used various DAWs such as Apple Logic Pro X, Ableton Live and FL Studio. However, his primary DAW is Presonus Studio One.
Speakers in his armory include Genelec 826OA and Genelec 804OB studio monitors.
