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.

Jordan Vico Vibe Tremolo

Not really a vibrato circuit, but a nice sounding tremolo. This layout is based on the schematic drawn by LucifersTrip on the FSB forum. I've increased the value of the film capacitors from 100n to 220n to reduce the maximum speed a little and make it more usable. People seem to have used anything from 100n to 500n for those caps, so there's room for experimentation there. I also laid it out to utilize onboard pots. It will fit nicely in a 1590B. Just drill the holes for the pots 1.2 inches apart.



The 6V8 diode is a zener, by the way.

  3. Hello!
    Would you please make a layout for the Easy Vibe. There are a few versions of this little beast:

    I really love your way to make the PCB layout.

    Thanks a lot!

    1. Thanks. I've gotten a request for that circuit before, and I've tried to lay that thing out several times. I'm pretty sure I can't make a better layout than what RG already did with that first link you posted. I would just etch his layout if it were me.

    2. I think you're underestimating your talent! You make very nice and clean layouts.
      I'll give it a shot in the first link I posted, for sure.
      Thanks again!

  5. Hi, can i use another diode for the 6v8? greetings from argentina, love this blog :)

    1. That needs to be a 6.8v diode like the 1N4736 or similar.

  7. Hi,
    the 4001 is wrong way round, so you get a short circut.

    1. Yeah that will probably be fine. Just use a socket.

  10. I have done but it doesn't works... the amp sounds intermittent shots but it doesn't cut the sound. The diode 1n4001 is wrong placed, isn't it? I have used c549b transistor and 570k resistors (470k + 100k) in place of 560k. Anyone could help me? Thanks.

  11. I built it. And I even managed to put everything in 1590a. But I have a problem. The sound does not change when I press the button. Clean sound in any position. I already checked everything I could. Please give me advice.

  12. the hfe of the transistor may alter the speed range of the tremolo, but should work. at least that happens with the magna vibe, that has a similar LFO. just a note
