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.

Jack Deville Boost Tiger

Here's an op-amp based boost circuit from Jack Deville (Mr. Black Effects). He was kind enough to share his schematic a couple years ago on FSB. I stumbled upon it and thought it would be a good addition here. It should easily fit in a 1590a, and you can probably board mount the pot too.


  1. I builded this pedal and works fine, thank for!!!

  2. Sir what is "1-boost-3" in the diagram? Log of pot number 1 and 3? How about log 2?

    1. The pad for lug 2 would be that pad right between the ones for 1 and 3.

  3. Low pas filter & bass boost?
    Only Bass Boost?

  4. Done, and great sound with a lot of volume. Thanks for the layout

  5. An amazing pedal ... great sound, and with my triple wreck wampler clone it's wonderful. thanks again for this beautiful work.
