Will this work? (Schem)

So I'm in need of a buffer that will Split the signal (for the "detector in" on my Boss HR-2) and be able to invert the signal if required. I've been searching around a bit, and have put together a schematic consisting of an inverter, an AMZ superbuffer and an extra OPamp with a seperate output.



Now I have very limited knowledge of audio electronics (currently studying it), so I would be very grateful if anyone would take a look at the schematic and tell me if there is anything that can be done differently or things like that.

Your help is appreciated.

Why do you have 4 opamps wired to the one output?

This type of question is popping up a lot all of a sudden (or I just haven't paid that much attention before).
B Tremblay posted this link that potentially solves all my problems, so maybe it does for you too:

and to rockhorst:

I've read about the Splitter-blend, but I don't think that the inverter from there will be easely implemented into the superbuffer..

I'd just like my circuit cleared (knowing that parts like the Vr, inverterstage and the seperate output will work) before I order the parts for it.

Yeah your schematic looks correct, you could probably simplify it a lot but it will work.
You might want to a add a resistor to ground after the output cap on the detector out, and you might need a pulldown resistor on the input of the invertor to stop it popping when you switch it in.
