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.

Electro Harmonix LPB-1

Got a request to redo the LPB-1 with the pot board mounted. Can't say I'm opposed and it only took about 5 min to layout. :) Easy fit in a 1590A. If you want to make the Screaming Bird treble booster, replace the two 100nF caps with 3.3nF.

  8. How do I connect the on / off switch? in fact, how do I connect the switch in all the diagrams on the page, since almost none say how to make the connection?

    1. Go to the general layout notes tab for off board wiring

  10. so this works, but it doesn't work with an LED. When I hook up an LED it seems to siphon off too much power and just shuts off?

  11. Why are some of the resistor values of this version different from the previous version? Is it to have more common values? Do the new values change anything audibly?
