BOSS RPS-10 Pitch Shifter / Delay

Thank you for looking.
This is a recommended item for those who know (lol). It's a half-rack pitch shifter/delay from the Micro Studio series, released in 1985.

The pitch shifter with ±1 octave change produces a mechanical sound that can only be achieved with this unit.
The delay features a reverse mode (INV:Invert), which is popular as a noise machine that creates unique, unconventional sounds.
Since it's a half-rack size, we're including a half-rack mount for integration into a 1U rack.

Requires separate AC adapter: Powered by a standard 9V center-negative power supply (100mA).
