Ivy Pedals is proud to present the Filter IV - a multi-mode analog filter - in our brand new SUNSET colorway. TWO of these pedals have been built. The Filter IV is a versatile audio tool capable of a variety of filter types, shapes, and sounds. Featuring two independent analog filters (a low-pass filter and a high-pass filter), each with independent level/frequency/resonance settings, all of your filter needs are met in one pedal.
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.
Controls:
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. Default to ~2, 10 is razor sharp and 0 is ultra-flat
This pedal features true bypass switching and runs on a 9v center negative DC power supply.

The LPF cutoff on this specific unit ranges from ~250Hz - 23kHz
The HPF cutoff on this specific unit ranges from ~26Hz - 16kHz
These pedals are designed so that, while the HPF may restrict certain bass guitar frequencies, the LPF will pass that frequency range.
More details:
This is a unique pedal in that, rather than simply switching between modes, we have provided the basic building blocks with which the filter types can be made. If you're familiar with filter types, what happens when you mix them, etc., this can be an incredibly powerful tool for tone shaping, mixing, and more.
HOW TO MAKE THE FILTERS
(Set Q to 2 as default, adjust as desired, does not change filter type)
Band Pass = Switch up, volumes on, HPF freq. lower than LPF freq.
Band Stop (Notch) = Switch down, volumes on, HPF freq. higher than LPF freq.
Band Shelf (EQ) = Switch down, volumes on, HPF freq. lower than LPF freq.
Low-Pass = Switch down, HPF volume to zero/off
Low-Shelf = Switch Down, volumes on, HPF freq. at 0
High-Pass = Switch down, LPF volume to zero/off
High-Shelf = Switch Down, volumes on, LPF freq. at 10
