SHO--negative ground?

[youngstownguitar]

Hi- I dont have a ton of experience with this stuff but I have built a fuzz face before.

For my next project I want to put in the same enclosure a soulbender and a SHO.  Kind of like a sunlion but with different pedals.   I have it all figured out for the soulbender, I think, but the SHO is Negative ground right?  How can I make it so that it's compatible with a Pos ground like the soulbender?

Any links or tips would be appreciated--thanks!

A relatively easy way to do this is to use a charge pump to put out 9v+ and 9v-. That way you could use a single 9v supply to power both at once. You can find some more info about this and probably other methods on diystompboxes.com. There are a lot of threads about it. If you want a board for it, I could make one for $1. The Road Rage 2 is going to have exactly this (+,-9v) as well as the ability to run regulated 12 or 15v all off the same tiny board.
