tiny Giant regulated output

[Mgt280y]

Good evening,
Just finishing off my Bass cabinet 2 x 10 bass cab and am running it on the Tiny giant

Im looking at adding some additional curcits not decided yet, and want to run them from the regulated output provided on the TGA, i think its 11.6v but need to check once up and running, in terms of making this a 9v regulated supply can i us a vereo board run the reg output to this with a ground and then thru a 9v reg to give me a couple of 9v outs with a common ground to connect to my other effects
