I know the FS-77 operates on a positive ground powering system. So, a reverse polarity cable is used with my Strymon Ojai...

Same with the earlier FS-75???

Thanks!!

From the FS-75 instruction sheet-

This unit can also be powered by a well regulated 9volt power supply with a NEGATIVE centre and a POSITIVE barrel.

The FS-75 operates on a POSITIVE GROUND powering system so therefore requires its own power source or an individually isolated multi way power source.


Hope this helps

Awesome! Thanks! :D

Check the instructions. But as Stella says, I think you want a regular center negative cable. A reverse polarity cable (center positive) might damage it. The positive ground issues simply means you can't daisy chain it (you can , but it will be noisy as shit).

Yeap, read it before I tried, thanks again. Wouldn't want to damage it!
