【Product Name】 Boss PS-2 Digital Pitch Shifter / Digital Digital Pitch Shifter / Delay 【Product Description】 While there are many modern pitch shifters and delays with excellent performance and sound quality, the BOSS PS-2 has a unique sound that no other pedal can replicate. Its characteristic delay sound isn't overly "digital," and the slightly rough tone is appealing, unlike the overly hi-fi delays of recent times.
