Title: Adding LEDs to this circuit
Post by: guitarplayer08 on February 25, 2013, 01:40:51 AM
I am a beginner who just started making DIY pedals. I'm planning on doing a 2 ch TB looper with order switcher following this schematic I found here at madbean:

However, I would like to add LEDs for the 2 effect inputs (NOT for the order switcher). Anybody can give me some advice where to place the LEDs?

Sure!

On each switch, there is an empty pole - the leftmost one. Connect the middle lug to ground, and the top lug to the negative lead of the LED. Make sure to include a CLR (Current limiting resistor) in series with the LED, either on the negative or the positive side, it doesn't matter. The other end of the positive end connects to +9V.
