I think that you meant the RPS-10 MicroRack Pitch Shifter?
This unit must be pretty close to the PS-2 "Digital Pitch Shifter / Delay". I'm curious how the "INV"-mode of this unit sounds like - therefore it's on my "effects I want to try before I die"-list.
Thanks for your offer, but this unit is not really number one of my list. And it comes pretty cheap in Europe from time to time. I have seen one or two of them last year at eBay that only went up to 30 � or so.
