Paul Cochrane's Timmy

Often cloned without giving credit to where credit is due (cough*lovepedal*cough), the Timmy is one of the most sought after overdrives on the market today. And really, if you can afford one, just buy one from Paul C. He's a great guy. For those of you who can't, here's my layout.

      That's just a switch to engage D5 and/or D6. More info here:
      https://en.wikipedia.org/wiki/DIP_switch

      You could use a DPDT toggle instead. Wire the 2 pads for the DIP switch that connect to Drive 3 to lugs 2 and 4 (refer to the General Layout Notes page for lug numbering), and the pads that go to D5 and 6 to lugs 1 and 3. I think there are versions from Paul C. that are wired this way. Hope that helps!

    I'm mid-build on this one and don't see the output. Is it volume 2 to out?

      Yep. That's what's used in the original. I used a 4558 when I built this though. Worked fine.

    How could one wire a 3 way switch to perform the clipping tasks of the later versions? Thanks for so many great layouts btw!

    The scheme of the Lovepedal OD11 is almost a copy of this pedal, know you if I can use the same board? Maybe I have to ask less and try more... jaja

      Explore the site a bit more. There are actually 2 layouts for the Lovepedal version.

      Pots can have pretty high tolerances. It's probably fine.

    Hi Effects Layouts, i used LM1458CN Op Amp and the 37Kohm (actual measured Pot),and used your PCB layout.and tested sounds great transparent Overdrive,Thanks to Paul C. and to you Effects layout..this is VERIFIED!

      Post pics of your build, it helps a lot.Maybe is a bad solder joint somewhere

    Is there a way to wire the dipswitch slots in a way that I don't need to use a dipswitch and the pedal stays in the equivalent of the middle position toggle of the version 3.

    Another question, If I want to reemplace the dipswitch with a 3 position toggle, how i have to wire ir in this board?

    Excellent low gain drive pedal, just the right guitar frequenties!
    One problem i experienced was the Treble and Bass work way better with 50KC (anti-log) pots.
    Nice layout work!
