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.

Four Step Atari Punk Console

I thought I'd mix things up a little this week and post some synth circuits people might be interested in. To start things out, here's a modified version of the classic Atari Punk Console. This has a few additional potentiometers for more control and a more versatile version of this popular synth.


In the layout below note that VR stands for variable resistor as the schematic I laid this out from didn't have names for each control (there are 6, labeled A through F).



Pardon all the jumpers, 555s are uncooperative for single sided layouts. Haha

    1. Its pretty straight forward. Each VR is a pot. VR_A 1 would be pin one on pot VR_A. I don't think there is a pretty way to do this layout with all the off board controls. Just jump in head first and wire it up. I look forward to seeing your build.

    2. Hi, thank you for your answer.. I've tried it and it works... but not all of the potentiometers seem to be working.
      On your layout, the VR_A for example, where it says: VR_A 2/3. is it pint 2 connected to pin 3 and both to the correspondent input / little hole?

      I appreciate your response. Thank you!

    3. Yes, jumper lugs 2 and 3 on the pot with a wire, component cut off, whatever you prefer... Then run a wire from that connection to the 2/3 pad.
