Ashdown Type 23 Three Band Filter vs Keeley Neutrino V2

The Ashdown Type 23 Three Band Filter and the Keeley Neutrino V2 are both pedals sharing mid-forward. The Keeley Neutrino V2 leans dynamic.

Similarity
citedBlended 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. Shown only within a gear class, and only where there's enough evidence to be meaningful.

Description

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.

The Keeley Neutrino V2 is a compact, all-analog opto-coupler envelope filter and auto-wah that creates a touch-sensitive wah sound from your pick attack. Hand-selected opto-couplers, described as higher grade than those in vintage originals, give it a smooth, vowel-like, vocal tone. It offers three filter ranges, two sweep directions, two frequency-center ranges, and a Peak control for shaping resonance, with true bypass to avoid tone suck. It suits funk, fusion, and expressive playing where dynamic filter movement adds vocal character to lines. Simple to dial in for a satisfying auto-wah, it is a small, focused envelope filter, though some players find its output can sound thinner than they expect at certain settings.
