This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

Dan Armstrong Green Ringer

Here's another Dan Armstrong effect. It's part ring modulator (when playing chords) and part octave (when playing on the neck pickup, high on the fretboard with the guitar tone control down). For the clearest octave effect, match the diodes as closely as possible for forward voltage. It might also be worth matching the 47nF caps and the 10K and 22K resistors.

    1. Follow the schematic I posted on FSB and you'll be able to build it on this layout. The only thing you'd need to add is a 100pF cap from input to ground. The rest of the circuit topography is the same.

  4. if I want to discard the volume pot assuming the output reaches unity, then volume 3 would be the "new" output and volume 1 doesnt mind, right?
    btw great page, greetings from Argentina
