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.

VooDoo Lab MicroVibe

Here's the Micro Vibe from VooDoo Lab—aka, welcome to jumper city. Always seems to happen with vibe circuits, but this one will fit in a 125B quite nicely. Pretty standard adpation of the old Univibe with speed and intensity controls. Set the trimmer to 250Ω (and be careful if you adjust it since there's no protection/limiting resistor). Schematic can be found here.

  1. Thank you! Very useful layout. Good luck!

  2. About the LDR diodes, which would be the best dark resistance value? There are multiple LDR versions and values in megaohms, which ones are the best for use in this circuit?

    1. I have bought a set and lamp from Banzai and small bear the small bear ones are in a madbean clone of the univibe and I get nice lush phasing ,I havent used the banzai set yet so I cant comment,

  3. I think it would be nice to add to the description that D1 isn't actually a diode, but a lamp

    1. You correct. 30ma lamp apparently. When I laid this out I think I just assumed it was an LED like the EQD Depths. I wonder if you could get a way with using an LED...

    2. I dunno, but thats what I'm going to try when I build this.

  4. https://www.youtube.com/watch?v=ZLo6EdFI31A i build but other layout of fsb with lamp and ldr, sound really good

  5. Definitely verified. Red LED’s work in the circuit. You should use TL062’s as TL072’s and 4558’s introduce ticking and other weird unpredictable noises. Fun circuit to build though.
