Op Amps and the stereo jack kill switch
« on: November 27, 2008, 09:14:18 AM »
I've not been overly dedicated to the hobby of building stompboxes and when the bipolar power circuits I built didn't seem to work properly, I toughed it out using dual batteries and simply pulled them when I wasn't playing.

After modding my overdrive a bit, it seems reducing the multipliers solved the issues with the bipolar circuit..maybe I was just trying to draw too much power? Dunno don't care because now I'm able to power it with a single battery or a wall supply.
My question is, how do I use the stereo jack to switch off the circuit when the battery's ground can only be directly connected to the op amps ground?

Am I actually supposed to run the "virtual" ground to the ring?
