The Boss PS-2 Digital Pitch Shifter / Delay is a legendary vintage multi-effect pedal from the late 1980s, combining crystal-clear digital delay with expressive pitch-shifting and detuning functions. This particular unit, serial number CB89770, is an original Japanese-made version featuring the sought-after blue label, representing the classic era of Boss manufacturing known for its precision and reliability.
The PS-2 includes four main controls: Balance, Feedback, Fine, and Mode. The Balance knob sets the mix between dry and effected signals, Feedback adjusts the number of delay repeats, and Fine allows precise tuning of pitch shift or delay time depending on the selected mode. The Mode selector lets players choose between several pitch-shift intervals, chorus-like detuning, short and long delay times, and hybrid settings that blend both effects.
Praised for its distinctive tone and experimental flexibility, the PS-2 is capable of everything from subtle doubling and ambient delay textures to wild pitch sweeps and shimmering harmonized leads. With its warm, vintage digital sound and Made in Japan build quality, the Boss PS-2 remains a favorite among collectors, sound designers, and musicians who appreciate the creative possibilities of early digital technology.
