The Intensive Care Audio Vena Cava Filter is a distortion with an auto filter and ring modulation used for the treatment of Bland Guitar Syndrome and Excessive Aural Dryness.  Used regularly, the Intensive Care Audio Vena Cava Filter can provide effective relief from these, and other music and instrumentation related conditions.

All Intensive Care Audio boutique effects pedals are built in London, England, using high quality components and featuring soft touch, relay based true bypass.  There are two soft touch footswitches, the left is Bypass, and the right is Tap Tempo.

The Intensive Care Audio Vena Cava Filter features 8 controls, there are therefore a range of available remedies.


  • Wave Function: An 8 position rotary switch allows you to select 1 of 8 available LFO waveforms. From left to right these are Random Slopes, Random Steps, Sweep, Sine, Triangle, Square, Ramp Down, Ramp Up
  • Freq: Sets the frequency (speed) of the LFO.  The speed (and waveform) of the LFO is indicated by the LED above the FREQ control
  • Ring: Sets the base frequency of a ring modulator which is swept by the LFO along with the filter.  Turning fully clockwise disengages the ring modulator.  At settings below 12 o’clock the carrier frequency becomes inaudible and provides an interesting stuttering effect. It can also be set to create octave down effects, which when swept by the LFO, moves around with the wave shape set by the Wave Function
  • Ring Switch: This removes the LFO controlling the ring modulator frequency allowing the ring modulator to be set at a specific frequency.  The LFO will continue to sweep the filter
  • Voice Switch: Selects between two voicing options for the filter.  One is a narrower notch with emphasis on high frequency content
  • Volume: Sets the overall output volume of the effect
  • Peak: Sets the depth of the LFO controlling the filter notch and the ring modulator frequency
  • Blend: Sets the mix between distortion (fully anti clockwise), filtered and ring modulated distortion (fully anti clockwise).  Use in conjunction with the Peak control to set intensity of the overall filter effect
  • Gain: Sets the gain of the distortion.  It ranges from a very mild overdrive to a heavy, fat distortion.  At lower gain settings the filtering effect becomes less pronounced
