Title: LED Wiring Question
Post by: kinski on October 12, 2012, 04:04:37 PM
So I built the following layout below. Its a true-bypass looper with two switches. One momentary and one latching.

I know there is a 0v and TO LED marking, but I still can't seem to get the LED to work. I'd like to use a DC Jack and a 9v battery. Could anyone here please help and let me know how to properly wire up a DC and 9v to power an indicator light with this layout? I've tried a bunch of things and still can't get it to light up!

Look at page two of Bean's standard wiring doc (http://www.madbeanpedals.com/tutorials/downloads/StandardWiring_MBP.pdf). On your drawing, the 0v will go to the sleeve connector on your guitar input jack. The To LED is represented by the blue wire in the doc going from the footswitch to the flat side of the LED.

You'll want to use a TRS jack for your guitar input. The FX out and FX in jacks should be TS jacks with shorting contacts. Wire the shorting contacts from the FX out and FX in together. The output jack can be a regular TS.

If you don't get it, this should do it for you.

Thank you oldhousescott and electricstorm! That did the trick! What a useful pedal this is. Especially the momentary option.
