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.

Greer Amps Southland

 Turns out the Southland is pretty much the same circuit as the Lightspeed, but with some hard clipping diodes thrown in the middle (and a couple value tweaks). Figured I'd make a new layout with space for the diodes. This layout uses the same drill template as the Lightspeed.





I ended up building a 2-in-1 with this and a Lightspeed and highly recommend it. If you'd rather a fabricated board, check out the LightLand on the store.

  1. Two new layouts in the same month?
    Nice!
    Thanks for all your work

  2. Hey David! Thanks for posting this one. It’s not working with the BAT41s in their positions as shown. Also tried 1N34As in case it was a bad pair of diodes. The Light Land schematic has these (D6-7) going to Vr instead of to ground as in the layout. When I pull D6-7, it fires up pretty much like a juiced Lightspeed. Sockets FTW. Any ideas what could fix the problem? Reroute to Vr between 4k7 and 220nf?

    1. Thanks for letting me know, Orion. Fixed and updated the image above.

  4. I made the first layout on perf and it didn't work. I managed to take it apart and put it back in the new layout and it works well! Really good pedal, bought the pcb too.

  5. Shouldn't the PCB fabrication image (bottom right) be mirrored?

    1. Not if you're using the toner transfer method. If you're doing photoresist, you're printing to transparency, in which case just flip the transparency around.

    2. So if i use the toner transfer method, the circuit will be mirrored. After that i will have to place the components on the underside, right? The wires will be seen on the copper side of the pcb for soldering, right? i apologize for dumb questions, i'm totally new to this

    3. No, print it as it is in the transfer pdf and the transfer process will mirror the toner onto the copper.

      If you've already etched a board and it came out mirrored, the only component you'd need to place on the copper side would be the IC. The pots would be backward as well and you'd have to put them on the component side. At this point you'd be having a hard time getting them to fit on top of resistors and caps unless you're using long leg pc mount pots or wiring them off board. Probably easier to just etch a new board that's not mirrored. Hope that helps.

    4. Thank you for your prompt reply! So if i'm doing everything right, all the components (including the IC) will be mounted on the "other" side, and only the pots will go on the copper side, right? No, i didn't etched a board yet. I've just ordered all the materials i need and give it a try next week :)

    5. Correct, everything but pots goes on the component (top, non-copper) side. Like this:

  6. Hello :)
    Is it possible to get the gerber file for this one?
    Thanks for the great work, keep it up!

  7. Hello :) I have a couple more questions about building pedals in general.
    How do i know if i need to use 0.25W or let's say 2.00W resistors for example?
    Also, does it matter if i use metal or carbon film resistors?
    Same question for capacitors, does it matter if i use film or ceramic ones?
