Ivy Pedals is proud to present two new Filter IV builds in the Sunset colorway. Electrical specs are the same, except for some added output gain. Filter IV is a multi-mode analog filter effect pedal. Featuring two independent analog filters (a low-pass filter and a high-pass filter), each with independent level​/​frequency​/​resonance settings, the user can achieve a wide variety of filter types for an all-in-one filtering​/​tone shaping​/​EQ​/​mixing solution. The Filter IV is capable of seven basic filter types: Low-Pass, High-Pass, Band-Pass, Band-Stop (Notch), Low-Shelf, High-Shelf, and Band-Shelf. These filters can be achieved by using the right settings for the center switch, frequency, and volume controls. Using different combinations of setting yields different filter types. -CENTER SWITCH - this switch puts the filters in series or parallel. In Series, you have a band-pass, and in parallel, you are mixing the filters together, which allows for shelving filters, using a single filter, and the notch filter. *(1 each for both the HPF and LPF)* -Volume - Sets the level of the filter output. Mix level when in parallel. -Frequency - Sets the cutoff frequency of the filter, the point at which the filter starts. LPF is 'off' at 10 and HPF is 'off' at 0. -Q (Resonance) - Sets the 'quality factor' of the filter, adding a sharp peak near the cutoff frequency.
