TC Electronics Mojo Mojo Overdrive

 Per request.

The layout stays mostly true to the schematic. One half of the op amps was unused to I used it for buffered Vref which doesn't hurt. Quite an interesting design if a bit over engineered.:-)

  1. Fuzzhead- I could kiss you! - if Bigger Brothers didn't make me sign a form promising I wouldn't. Time to break out the vero

  2. I was about to ask why you left some resistors and caps transparent, too dumb to notice they have cuts below them, poor me. I actually color invert in photoshop and work my way, marking stuff, adding annotations, which led to the confusion.

  3. not getting any sound out of this. the only change i made was using film caps for the 100nf on pin 8 instead of the ceramics pictured. could that actually make a difference?

  4. nuke that 1k resistor that goes after the 5817 and the pedal works. otherwise it cuts the input voltage of your op amp to 1.5v and you get no sound at all

  5. 1k series resistor and series schottky diode at the power supply??? A schematic on Reverb has a 1R resistor. With 1k, the voltage would be to low for many opamps.
