They're mostly standard tuning, except for the low B which occasionally gets dropped to A, as we're currently doing Citizen Erased as a cover. As for the Sustainiac, I'm normally used to Fernandes Sustainers but they don't do anything for 7 string. Plus from what I can gather they've become kinda flaky in their business dealings, so I guess Sustainiac is picking up business at their expense.
Installing a Sustainiac is a lot easier then a Sustainer. If you're not afraid to solder or know somebody who can. Like I said, the Sustainer installation guide only covers installations in a Strat or a Les Paul. Anything else and you're on your own. The Sustainiac Nazi on the other will give you detailed instructions based on the information that you will give him.
As for modding a guitar, lots of pickup manufacturers have good support pages on their sites with detailed PDF's for a shit ton of wiring variants. Do you have anything in mind?
