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 Dunlop Blue Hippo Optical Tremolo is a vintage reissue tremolo pedal from Dunlop, recreating the optical tremolo circuit of the classic blue Univox Hi-Flier tremolo from the late 1960s. Optical tremolo circuits use an LDR (light-dependent resistor) for smooth, natural amplitude modulation with the rounded waveform character associated with vintage optical tremolo pedals. The Blue Hippo was a limited-production Dunlop reissue.
The Universal Audio UAFX Flow is a compact vintage tremolo pedal that emulates classic tube-powered amp tremolo, delivering the woozy, pulsing sound of vintage Fender amps with impressive fidelity. It offers three modes: 65, modeling the optical tremolo of mid-1960s amps like the Deluxe and Twin Reverb; Square, a harder-edged choppier waveform; and Dharma, a harmonic tremolo voiced after late-1950s and early-1960s Fender amps. Its range spans gently pulsing throb to machine-gun chop, and the harmonic mode adds a lush, phasey movement many players find unexpectedly rewarding. Simple to use yet richly authentic, it is an affordable, great-sounding choice for blues, surf, indie, country and vintage-flavored tones in a small true-bypass enclosure.
