OK so I got a little Casio SK10
I want to add a jack so I can plug it in an amp or mixing desk of the PA (and use it with FX)
now what do I do ?
I want it so that the little internal speaker is automatically disconnected whenever a jack is inserted in the output, and that the internal speaker still works when there's no jack connected.
I have one of them circuit switching jacks
What do I connect where ?
