I have now successfully built Magnus Modulus, a big'un
works EXCEPT! The LED's D2, D6 and D8 The first one is the tremolo LED, I believe the others indicate modulation (?) the LEDs are the only piece the documentation doesn't go into much detail about (understandably)
I can't get them to work. Correct resistors with them, ordinary LED's, even tried switching direction as the diagram is fuzzy on the direction of the negative side of the LED. I couldn't even find the modulation LEDs on the schematic to verify.
Any ideas what I should look for in trouble shooting this? I've tried a number of things and am mystified
Obvs. doesn't affect delay functionality but still an irksome lack of closure to the project
Help appreciated!!
