Cave Dweller 1 - Added Volume Booster

[MullisMan]

I'm thinking of tacking on the IC baby board boost at the end of the CaveDweller 1, I wasn't sure if the effect ran at unity volume but I'd like to be able to boost it a little or a lot.  I guess I could use any boost on the end but wondered if this would effect the delay circuit at all.  I'll use coupling caps in between circuit stages, and I was thinking of not using the split rail supply for the boost to minimize parts count.

Anybody see any technical issues with trying this?

Just to show what i'm doing, I've included the Eagle schematic with what I have in mind.  I took my 9v power for the boost at the end from the regulator in the delay circuit.  Will this be ok?  I've not used regulators much at all.

Any help at all would be appreciated.
