A-B Switching

Hi all!

I built today a simple A/B switch using a DPDT footswitch so that I can drive my guitar's output into 2 different amps,  but NOT to use them simultaneously. I used the one side of the switch for the signal, and the other to control 2 leds (for status), but when the switch is on A, there is a little signal passing through to B and vice versa. Is this because I should be grounding the output I am not using? eg. when using A, B should be connected to GND? If yes, i will lose the capability of controlling the leds...

Any comments are welcome!

Thanks
