dpFX Pedals Variable Low Pass Filter
Dpfx Pedals · pedal
This entry covers the dpFX Pedals Variable Low Pass Filter, a boutique filter pedal with a sweepable cutoff range spanning roughly 220 Hz up to 16.5 kHz based on its own listed specifications, letting players progressively roll off high frequencies anywhere from a subtle darkening of the top end to an extreme, muffled low-pass effect. A low-pass filter like this works by allowing frequencies below the cutoff point to pass through largely unaffected while attenuating everything above it, giving guitarists and bassists a tone-shaping tool distinct from a standard passive tone control, with a far wider and more precisely adjustable sweep range than most guitars' onboard controls offer.
