Friedman BE-OD

"Designed by tone-guru-to-the-stars David Friedman, the BE-OD overdrive pedal faithfully captures the sonic impact of Friedman’s legendary BE-100 amplifier–known in some circles as the Brown Eye, and favored by serious musicians the world over.
The BE-OD overdrive delivers authentic tube amplifier sound from a compact pedal with the controls needed to shape your tone, including volume, gain, tight, bass, treble and presence. These responsive knobs will take you from light, slightly broken-up overdrives to straight-up gain nirvana"
Original FSB thread and schematic available here.

  4. Great post, as usual, congratulations! It would be really nice if all of the projects included schematics, like this one. Keep up the good work!

    1. There are reasons they don't include the schematics. They are frequently mentioned.

  7. Diodes similar to bat54? I think i saw a forward v of 0.35 so.. 1n34a? Or just fav clippin diodes?

    1. You can try that, but in my experience Ge diodes have their own "taste". I'd probably use BAT41, it is readily available from Tayda. You could try BAT46 as well, though those have lower forward voltage of about 0.25V

  8. What about C1 and C2?
    Really a GOD/good job...thank you from Italy

  9. Thanks Alex!!I was waiting for that one!I hope it will be close to the original!!

  10. Those BAT54 are a different shape than the others?

    ReplyDelete
  11. I used BAT85s instead of BAT54s as both have similar specs, 0.8v forward voltage.

    2. Technically speaking yes but you cannot substitute them because the TL074 has a different pinout and obviously one one point for voltage and ground/negative voltage. You would have to change this layout quite a bit to use TL072 in its place.

  14. Do they make the bat54 like a bat41 or they only made with the 3 legs. And is there something special with the bat54. Is more forward voltage better or less voltage better.

  15. The clr is usually offboard for the indicator light on the pedal. Anything between 2.7k to 4.7 is isually fine.

  16. Id also like to verify this as working i havent seen a clear indication that it was verified but thumbs up here.

  17. Anyone get low output volume and the Tight also increases or decreases volume?

    ReplyDelete
    Replies
    1. Max volume and max gain, and it's playable and not loud.

      Turning Tight Ccw increases volume and bass. CW decrease volume and more treble

      Delete
  18. Also, used bat41 and 3mm red leds!

    C2: started with 10nf. Decrease for more treble and increase for more bass. I think 1uf sounds good in mine haha

    C1: started with 470pf and tried 100pf, but was a bit bright, so back to 470pf

    1. Is it "verified??" What are the reasons the schematic link and schematic are not posted also?!? Personally, this is missing a mid-control and other features like variable resonance which would make this pedal muc better. How to incorporate those features if the schematic and design not included??!?

    2. Sorry mate but I don't really like people complaining. Instead of spending the time writing this message you could have simply read the circuit introduction (where the "link" is) or search it yourself on FSB as I did.

    3. Whoah. Another dickhead! Where can we send your money back?

      Even newcomers should know better than that.

      On an important matter: stay strong Mark! We are all with Manchester! I was in the London Tube in 2005 and all I can say is "Fuck those religious terrorists cunts"!

  20. Everyone check out "rmroza"'s comment about the original. Sounds like he's spent a good amount of time with it and confirmed the gain knob doesn't do much and that "OD" is an understatement, enough to want to take an original apart and enhance it haha

  21. Heads up. You can get 50pcs of bat 54 on aliexpress with delivery for $1. You can also get 10 sot23 adaptor boards for diodes and transistors 10 for $1. So 2 bucks and about 20-30 days . It worth it i
