A multi-purpose analog operator for adding and subtracting signals
PGO is a multi-purpose analog operator for adding and subtracting signals. It is designed to cover as much functional territory as possible, while also remaining compact and intuitive. PGO is capable of many basic processing steps, such as amplification, attenuation, inversion, addition, subtraction, averaging, and level shifting.
PGO is offered as a Fully Assembled module with DC barrel and EuroRack power cables included, or as a Partial DIY Kit with SMT assembly and front panels only. All variants include alternate red, green and blue front panels.
These merchants probably sell this module. Huh?
