I'm currently building a custom pedal, but I want LEDs on the side of the pedal to light up when a note is played with my guitar. I don't really know much about the guitar signal itself, am kind've following guides, so some help on how to do this would be great.
Cheers. |

Well if this is say a Distortion Pedal you could put the LED"s in the Feedback loop of an opamp and they would Lite every time you played a Note and they would also create the Distortion sound.....
Another way I suppose would be to set up a Clipping detection curcuit and set the Clipping threshold really low so every time you played a note the LEDs would lite.......
What type of pedal are you thinking of building??? |

| It is infact simple switching box which I may add bass and treble controls to. |

You need a "colour organ" circuit driving LEDs - google !

Thanks a lot for the reply.
I've been looking over colour organs, but I have one last questions.
A circuit like this for instance: http://www.aaroncake.net/circuits/organ.asp
How could i change the mic input to an input jack for guitar, and would it still work?
Any other recommended circuits would be great, cheers. |

I would NOT connect this or similar circuits to a guitar as they are LIVE to Mains !!!!!!!!!!!!!!!!!!!!!!!!!!!nasty.
I have seen low voltage versions running off 12v which would be safe.
Warning over.
[A guitar could be used if the components before C3 were deleted and the input into C3 via a level control.]
Take care.
