Pedal Pitch Shifter Delay Boss Ps-2

The PS-2 was the first pitch shifter made by Boss and one of the first pedals with dual boards. It works both as a pitch shifter and a digital delay and it is perhaps surprising that it doesn't use the same chip as the DD-3 and DSD-3. Pitch shifting is limited to one octave up or down while maximum delay time is 2 seconds.

The earliest PS-2s suffered from high frequency noise. This was alleviated from serial number 845800 but earlier units can be modified to the later specification by changing 3 capacitors.Production was moved from Japan to Taiwan early 1992.

The PS-2 has a total of 6 different modes

• Up to 125 ms delay
• Up to 500 ms delay
• Up to 2 seconds delay
• Set pitch shift manually
• +1 octave
• -1 octave
