Two effects one housing
Can I put two effects into one housing, and use just one 9v power input as long as I have the amperage for both effects? Everything else would be kept separate...Wanting to do a dirt and reverb combo. Would I need to isolate things or could it be as easy as splitting the 9v supply? Just getting into building DIY so be easy on me....

Re: Two effects one housing
Yeah, definitely can put 2 (or more) effects in one box.
Imagine you have a single adapter and one of those power splitters. It would be the same thing as connecting two effects in one box.
I would use this wiring diagram. It grounds the input of each effect when not in use to prevent oscillation/noise. You could also wire the 3pdt switches using the normal, non-grounded input true bypass wiring.
Another option is to use switched jacks. You have to use double the jacks (input and output for each effect), but it gives you the option of inserting effects in between the two. I can explain more (or link you to some reading material) if you are interested.
Good luck!

Re: Two effects one housing
I couldn't remember where I first learned how to use switched jacks for multiple effects in one box. I should have known it was Geofex.
Switched jacks are explained in this article: Jimi in a box.
Geofex is a great place to learn.
