GuitsBoy Posted March 3, 2005 Report Posted March 3, 2005 How do I wire up a stereo output jack to cut power to the electronics when I unplug? Is the negative pole of the 9v batt hooked to the common ground? Will that introduce noise? Im working on a thinline tele with an acoustic preamp, and I dont want to have to remember to switch it off every time. Thanks! Quote
thedoctor Posted March 3, 2005 Report Posted March 3, 2005 Okay, lets not call it stereo. Lets call it TRS (tip, ring, sleeve). The negative from your battery goes to the ring terminal of the jack so that when a 1/4" plug is inserted, the ring and the sleeve(ground) are connected, thereby providing negative battery to the ground of the beast. Unplugged, no negative. Quote
