Intensive Care Audio Vena Cava Filter

Overview

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

All Intensive Care Audio pedals are built in London, England, using high quality components and featuring soft touch, relay based trued bypass. There are two soft touch footswitches, the left is Bypass and the right is Tap Tempo. No.Tom Guitars are pleased to offer Intensive Care Audio effects pedals as the exclusive London dealer. 

Controls

The Intensive Care Audio Vena Cava Filter features 8 controls:

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. Set correctly it can also create octave down effects which when swept by the LFO moves around with the wave shape set by WAVE FUNCTION.

Ring Switch - This switch removes the LFO controlling the ring modulator frequency so the ring modulator can 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) and 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.
