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 Maestro PS-1A Phase Shifter is a vintage analog phaser introduced in 1971, prized for one of the lushest, warmest phase sounds ever produced. Rather than a sharp modern sweep, it delivers a warm, organic, and often subtle swirl with three speed settings, including a distinctive braking transition between fast and slow that sounds like a jet engine winding down. It defined classic 1970s phasing, heard on the electric piano of Led Zeppelin's No Quarter and on recordings by Steve Howe and Ernie Isley. It suits psychedelic, classic rock, and vintage tone enthusiasts who want immersive, lush movement. Some high-end loss occurs when engaged, easily corrected with a buffer upstream.
The Tru-Fi Ghost Vibe is a recreation of the classic Uni-Vibe effect built by a self-described Hendrix tone enthusiast, developed by referencing six modern vibe pedals alongside original 1968 and 1969 Uni-Vibe units to get as close as possible to the vintage 1968 sound. It includes the three core controls of the original, Volume, Speed, and Depth, labeled Intensity on the vintage unit, plus a Vibrato and Chorus mode switch. An internal buffer and normal switch mode selector makes the pedal brighter and better suited to sitting ahead of wah or fuzz pedals when buffered, or delivers a slightly darker, more vintage-accurate tone when left unbuffered. It runs on a 9V battery or power supply with voltage internally converted to 18V for extra headroom. Suited to psychedelic and classic rock players chasing authentic Hendrix-era Uni-Vibe modulation and pulsing vibrato textures.
