We have never reviewed a bad pedal from our friends at Fairfield Circuitry, and luckily that trend is going to continue today. The Long Life Parametric EQ is an extremely unique effects pedal, one that’s sometimes hard to categorize. A filter effect with wide range and application, this versatile machine combines tilt and notch/boost equalization around a 2nd-order state-variable core. In short, it’s a one-band parametric EQ with some gritty extras – let’s see what they are…
The Long Life’s main control is the big Freq knob, which sets the corner frequency of the filter. This knob can also be controlled via an external expression pedal plugged into the EXP jack on the side (see our demo below). Q is a resonance control; before noon you get softer equalization, with a more aggressive stance past 12:00. Gain lets you choose negative or positive gain on the bandpass filter section, letting you notch or boost the selected frequency.
Volume is a unity gain control, or an output signal control, with a flat response around 2:00. Tilt lets you, well, tilt the frequency response around the center frequency. With a flat response at noon, extreme left settings produce a low-pass response; to the left, high-pass. This leads to various degrees of shelving, with a wide range of tones to explore. The Q (resonance) and F (frequency) 1/8″ inputs are for use with CV, from sequencers and keyboards, as well.
Utilizing a flexible tone stack for desired response, the Long Life also works great stacked before or after other pedals, for dramatic emphasis or de-emphasis. The fully variable Q will also launch you into self-oscillation territory, if you like being led down those types of paths, too. The Fairfield Circuitry Long Life Parametric EQ is one that must be heard to be truly understood, and we’ve tried to do our best to explain it in our demo below. Thanks to the Fairfield crew for letting us attempt to harness the power of yet another one of their machines – let’s just see if you all can do the same.
