Angry and aggressive all in one! The DVK Technologies Hairball truly takes the concept of Overdrive and Boost as a combination to near insane levels. The drive is quite high in gain with a custom voiced tone circuit. It also cleans up nice and responds well to your picking style and guitar volume setting. The Boost is where things get a little crazy. Massive level increase is possible and you can select Full Range or Treble Boost to suit your taste. The Hairball, dedicated to gagging cats everywhere.
