I hope that y'all can help me out. I need to build a kill box for my son. One with 2 inputs and two outs with LEDs. This will be used to kill click and loop backing tracks from a laptop. He is our drummer at church and needs to be able to control what is fed to the soundboard. Some of our click tracks have a backing track... and if we change keys he needs to be able to kill the loop himself and not have to depend on the sound person to mute the track. At the moment the stereo signal is split into 2 mono 1/4 plugs that go to DI boxes. This device would go before the DIs... That make sense?:?: The box needs two mono ins and outs... two stomp switches and leds... Any ideas on how to go about making such a device??
