how would you add a 9v OUT to a circuit?

[pedaljunkie]

I'm building a GuitarPCB buffer with a tuner out for a friend of mine and he asked if there is a way to have a 9V OUT jack to power his tuner since its on a Pedal Pal (side car for a pedaltrain board).

Would this be an easy mod?  If anyone could give me a bit of info, I would be much appreciative.

Heres the link to the circuit

If you're only going to power it with a DC supply, you just need to connect a second DC socket in parallel with the main one. This just takes the incoming 9 volts and sends it to the circuit and to the second DC socket, same as if you used a 9 volt daisy chain.

If you want to use a battery as well it might be a bit trickier.

Thats what i was thinking/hoping!  No battery..

Thanks!!

make sure the pedal he is powering off of yours has the same polarity, or it will cook his tuner...
