Title: Pork Barrel LFO indicator LED ground point...?
Post by: mgwhit on April 17, 2012, 06:44:45 PM
To add the LFO indicator, the Pork Barrel build doc says:

"Omit R39 from the PCB. Run a wire from the R39 pad on the right side of the PCB to one
lead of a 22k resistor. Attach the other lead of the resistor to the positive lead of a High Brightness 3
or 5MM LED. The negative lead the LED goes to the 3PDT switch to toggle it on and off with bypass."

If I were to connect the cathode of the LED back to the other pad of R39 would that just keep the LFO indicator light on all the time (i.e. even when the effect is bypassed)?  I'm assuming based on the schematic that that pad is just connected to ground.

that seems right to me. i often prefer rate indicator LEDs on all the time too.

Thanks!  I'm gonna try to rig it up to a plastic baseplate and I figured it would be easiest if I just had everything arranged vertically right there on the board.
