Hax controls are:  Tune. Crash, Blend, Hi/Low, and Bypass.

Tune determines the frequency of the oscillator that will be smushed up with your input signal.  The hi/low stomp switch determines the range of the oscillator.  The low range will allow for tremelo type pulsing, all the way up to sci-fi screams.  Hi range does not go as low, but the control is smoother and easier to tune.  The Expression pedal jack accepts a boss or Moog style expression pedal, allowing you to tune the Hax with your foot.

Crash casues the Hax to freak out, and make terrible glitching noises.

Blend mixes the effected signal with your dry signal, which can really help in taming angry computer sounds that you might be creating with Hax.

Bypass stomp engages the effect, and also connects or disconnects the power to the oscillator.

Hax accepts the standard 9v ac adaptor, center negative.  ENJOY!
