ANAPHYLAXIS FILTER - WASPsynth multi-mode filter with double LFO and distortion (#3.2024)
The ANAPHYLAXIS FILTER is a multi-mode filter with double LFO modulator for the CUTOFF frequency based the filter section of the notorious WASP synthesizer that was created by Electric Dream Plant in 1978. This standalone pedal version of the filter allows you to use it for the input signals of your choice. The FILTER MODE selector is a 4 position rotary switch (up to down: LOW PASS, BAND PASS, HIGH PASS and NOTCH) with the position indicated by small purple UV LEDs. The input signal is controlled with the GAIN control, that can boost even weaker input signal to overdrive the filter. A dedicated RESONANCE control determines the amount of RESONANCE at the CUTOFF point, that of course has a control knob as well. Furthermore the RESONANCE has two settings: EXTREME (up) and NORMAL(down), selected with a toggle switch. In HIGH PASS mode the filter can self-oscillate without any input, in case you need a high frequency SINE WAVE oscillator. In that case the FREQUENCY can be dialed in with the CUTOFF control. But the ANAPHYLAXIS FILTER can do more, as it has 2 build in LFOs that are modulating the CUTOFF frequency, with independent SPEED and DEPTH controls, which allows to generate a more complex modulation waveform. Each LFO has a RANGE toggle that selects: SLOW (down) or FAST (up) as well a 3 position toggle switch that selects the SHAPE: SQUARE (down), OFF (middle) and triangle (up). The fast LFO range goes well into audio range and enables you to create some very interesting frequency modulation filter effects. With slower rates, especially with the triangle shape and the 2 LFOs running at non-synced rates, even the most static sounding input get ‘alive’. The SPEED of each LFO is indicated by either red or green color in the big LED in the middle of the LFO section. The 1st stomp switch is TRUE BYPASS and if that is not enough, the 2nd stomp switch engages the DISTORTION, both with UV indicator LEDs. The level of the DISTORTION is controlled by the DISTORTION knob and the toggle switch next to it adds a TREBLE BOOST (up) or a HIGH CUT (down) setting to the DISTORTION. In the end of the signal path is a signal booster based on the EHX LBP1 with a global VOLUME control. The ANAPHYLAXIS FILTER runs on 9V DC and has a ‘boss style’ 2.1mm DC barrel plug socket with the negative pin inside. The enclosure is a heavy duty scavenged industrial engine power connector housing made from die-cast aluminum with a bottom plate made from found material and is painted in the industrial burnout camo pattern in matte black and bright yellow. Handmade by GRM for METSÄÄN.
