I am unsure if sharing a ground with an external amp and an internal amp would cause any issues?It can cause issues with ground loops or worse. Some amps require their output (-) terminal to be isolated from ground for things like current feedback schemes.
If you want it to be safe as possible, use a Cliff S2 style jack, which will be insulated from chassis, and also will allow switching of both the positive and negative wires.
Thank you! This is what I had suspected, but your answer confirms this. Much appreciated.
