Always On High Pass Filter

The Broughton Audio Always On High Pass Filter is a compact high pass filter effects pedal designed for low-frequency control on pedalboards. This pedal applies a 12 dB per octave high pass filter, continuously adjustable from 25 Hz to 190 Hz via a single control knob. The streamlined design omits a bypass switch for permanent signal processing, allowing for a smaller footprint that fits on a single pedal rail or can be mounted underneath a pedalboard. The pedal features a standard input impedance of 1MΩ and an output impedance of 100Ω. Custom input impedances are available upon request for compatibility with specific acoustic pickups. The Always On High Pass Filter is compatible with active and passive instruments, and can be integrated with other pedals, preamps, or effects loops. **Features:** - 12 dB per octave high pass filter pedal - Continuously variable cutoff frequency from 25 Hz to 190 Hz - Compact, always-on design without bypass switch - 1MΩ input impedance (customizable on request), 100Ω output impedance - Compatible with active and passive instruments - Suitable for pedalboard and effects loop integration
