Citation/mention fame — how often this gear is cited across artist rigs and gear discussion.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 Tinsley Audio Sir Henry is a boutique uni-vibe-style pedal recreating the lush, watery, rotary-like modulation of the classic Univibe. Used by Kenny Wayne Shepherd, it delivers warm, three-dimensional chorus/vibrato sweeps evocative of Hendrix and late-60s psychedelia. It suits blues-rock and psychedelic players wanting authentic, organic uni-vibe textures.
