Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement.

The Ashdown Type 23 is a three-band dynamic bass filter pedal from the UK-manufactured PRO FX series. Three frequency bands (high, mid, and low) are processed by independent voltage-controlled envelope filters that generate speech-like and funky bass tones. A single Sensitivity control sets how strongly the filters respond to playing dynamics. A switch on the pedal base varies the oscillation frequency of the selected filter for further tonal shaping. Requires 18V isolated power supply. Steel housing with anodized fascias and Neutrik jack sockets. Dimensions 63 x 108 x 120mm, 0.6kg.
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.
