DJ TechTools is a San Francisco–based company founded in 2007 by DJ Ean Golden as a blog and community hub dedicated to the emerging field of digital and controllerist DJing. What began as tutorials, gear reviews, and MIDI mapping resources grew into a manufacturer of its own controllers and accessories, sold through its online store alongside curated third-party gear.

The company is best known for the Midi Fighter line of MIDI controllers, built around Japanese arcade-style buttons and RGB lighting for live performance, finger drumming, and clip launching. The lineup includes the Midi Fighter 64, Midi Fighter Twister (a 16-encoder knob controller with RGB feedback), and Midi Fighter Spectra. Alongside the controllers, DJ TechTools produces the Chroma line of accessories — Chroma Caps (replacement knob caps for mixers and controllers), Chroma Cables (color-coded audio cables), and related branded gear.

Beyond hardware, DJ TechTools maintains an active blog, YouTube channel, and community forum that cover Traktor, Serato, Ableton, and CDJ workflows, along with a MIDI mapping database used by DJs to share controller configurations. Ean Golden has also been credited on the design of several mainstream DJ controllers, including the Vestax VCI-100 Ean Golden Edition and the Novation Dicer.

DJ Tech Tools has 11 products cataloged on Equipboard, including MIDI Pad Controllers, DJ Accessories, and Instrument Cables. Their gear is featured by 53 artists, with the strongest followings in Electronic, Pop, and Rock. Notable users include Shawn Wasabi, Joe Hahn, and underscores.
