Hey folks......I am making room on the board for a GR-2, and I noticed it says "9v" at the power jack. I have also read that it will accept a 9-18v on several reviews as well as the Wonderlove PDF. I have not been able to find a true "spec sheet" for this pedal, and it seems 3 Leaf takes them off the site when they move to the next evolution. Anyway, I have an 18v output left on my power supply so I'd prefer to run it 18v. Do any of you run yours at 18v? Have you noticed a performance difference? Thanks for the input!
When I owned it it felt to me like 18v made the filter less sensitive. Like it took higher sensitivity levels to open up the filter. Perhaps it has more headroom in that sense? Enjoy the pedal!
