  2. This can be tagged as verified!
    One of the best overdrives ever in my opinion. For the opamp I used TLC2262, works also great.

    1. I used a TLC2272cp fwiw. sounds good, gets nice and crunchy and the contour/accent controls are very interactive... if a not a little confusing at first.

    4. Nice!
      Royal Blue OD...no schematic on the web so we got to wait until it is traced...:-/

    5. That's too bad Fuzzhead. I do have a gutshot for you of my own Paul Cochrane Timmy 2017 (v2). The values are slightly different from the tagboardeffects layout as far as I can tell.

    6. I don't have a Timmy layout yet. Got to check out some schematics. So there are several versions of it?

      In the meantime, almost finished with a layout for Greer Southland OD which is related to Lightspeed...sounds interesting?

    7. Yeah there are 3 versions, v3 got rid of the ‘counterclockwise’ tone controls. I’ll take A look at the Southland, thx!

  6. Hello!
    I've finished it, but it sounds strange. I have a lot of clean signal mixed with some distorted one. This is how it sounds?
    Looking at the schematic, the 100nF from the second half op amp loop seems to be too big. I never saw one bigger than 4.7nF in that position. Anyone knows if it's OK?
