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.

Tube Works Blue Tube

Came across John K's vero of this circuit with a few mods (Mid pot, bipolar charge pump) and figured we needed a layout for it as well. Runs on 9-12v. Pots are all board mounted with the tube off board. Here's John's original layout.

  5. one question, according this schem: http://www.freestompboxes.org/download/file.php?id=26626&sid=c5972154d713f729e428f11df7ffa3ab&mode=view
    resistor from 7 leg tl 072 after cap 47n =100k, but David's layout has 100 ohm. Which variant right?

  6. the voltage of the resistors and capacitors remains the same?

    resistors 1/4 watts ?
    capacitors ?
