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.

Looking for a mid-range frequency booster? This one's apparently really good at it. Schematic and discussion on FSB here.

    1. Must have forgotten to upload it. It's in the Demeter folder now

  3. Can LF442 be substituted for anything else? Tried TL062 and OPA2134, but the circuit is giving out ultra low level sound through. Guess I may have made a soldering mistake somewhere, but can't spot anything. Either way - if LF442 is the only way to go, I'd need to import it to my country :/

  4. I used a TL072 while waiting for the LF442. Works fine accept for the constant overall boost. Mid control all the way down is not unity at all. I'll see what the LF442 will do but if you insert an output trim, the TL072 will work.

  6. @Effects Layouts: So mid2 is Out but I also have to connect mid2 to that pad in the board? Is that correct?

  7. Yes, I have the same question as JRDN - SO the Mid2 is both Out AND connected to a pad on the board?
