Mini Me No Chorus Effect (solved)

[Anonymous]

Hi there,

 

This is the 3rd Mini Me I have built.  This one is passing only clean signal when engaged.  No chorus affect.  Have adjusted the trimmer.  Nothing.  Here are the voltages on the ICs and a top board shot.  Will get an underside shot shortly.

And…. I’m a dummy. I wired the LED to the wrong pads on the bi-colour LED part of the breakout board, so was adjusting the trimmer when the effect was bypassed, rather than active. All good now!

Excellent troubleshooting!
