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.

EarthQuaker Devices Dunes

If the Palisades is too much for you, the Dunes has a much smaller footprint and less controls to get distracted with. Pretty standard Tube Screamer clone with clipping options and a couple tone shaping switches. Might be a bit of a squeeze but it will fit in a 1590B with board mounted pots.

    to those who build it, be carefull with the voice switch, as there is an insane volume boost when in the middle.

  4. Hi! 3 pots are in a row? Most of your layouts the center pot are off axis and it’s nice! Thanks for the layout. Maybe i connect the center pot off axis with some cable.

  5. I tried to reverse engineer this back into a schematic in Eagle so I could play with the physical layout, but I must have something wrong. Is there anyone willing to shed a little expertise on things for me. Any help would be greatly appreciated.

  8. Hi,
    I can get 2N7000G. Is this the same as 2N7000, if not, is it possible to use?

    1. I think the G is just a manufacturers marking. Should be the same

  9. Hello,
    please can you tell me something about the lead spacing of the different film capacitors or how I can calculate it by the count of the pinholes?

    1. The grid everything is designed on is 0.1". Lead spacing is usually 0.2" or 0.3" for film caps in my layouts.

  10. The clipping led on my build is not lighting up, I measure some voltage going through the led, but only 0,3V at max settings when not hitting the strings. Is this the same for you guys?

    1. The voltage goes up when I do hit the strings but not enough for it to light up

    2. It's not necessarily meant to light up, just clip the signal.
