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.

HAO Rust Driver

Here's another plexi-in-a-box pedal. Fairly simple in comparison to others. I've drawn 2 layouts for this one; one stock and one with an adjustable gain mod. The EQ switch is optional, as some who've built this circuit say it's pretty lackluster. The original uses an MC4558CN, but just about any dual op-amp should suffice (try JRC4558, TL072, NE5532, etc).


    Do it!

  2. @Maurus brother
    Are you built from this layout ?

  3. After correcting a mistake in my build it's working fine now. Really nice thingie!

  4. which is the function of diode 4001?

  5. Hi, I'm new in building guitar pedals, i want to know how I put the knobs and the switch

  7. I just build it. It sounds awesome. I wish I had etched the second layout with the drive mod, but I'll try to implement it to my board because sometimes its more distortion than you need.
    So if you plan to etch this. build the second layout from the beginning.
    Also the warm setting is too dark, even for my strat and I cant imagine what a les paul type guitar would sound through that, so change it to something less dark.

  8. How could I convert this to Bass? I am guessing something to do with changing 1 or all of the 100nf to 470nf?

    1. I'd start by upping the 56nF cap to 470nF and the two 100nF caps to 1uF.
