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.

09/06/17 Layout updated! Schematic and layout have now been corrected. Thanks to Ciaran, Pakrat, Destro and the others on FSB for all their work.
If you've already built the previous layout and want to correct it:
- Remove C2. The remaining 10n cap that connected to it becomes 100n and needs to go to ground instead of V+.
- Change the 120p between the TL074's pins 1 & 2 to 47p.
- Change the 100R resistor to 10R.
- C1 is now 47p.
- The 10n cap next to the trimmer is now 100p.
- The link under the trimmer (from lug 1 to lug 2) needs to be moved up one row (between lug 2 and lug 3). Eliminate the cut under the trimmer by jumping it left to right.

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

    2. Second. We do not post other people's work as that would be infringement on their copyright. Sometimes we do post a link to a forum thread where one can be found. Since we do not have any magic source for secret files, one should be able to find the schematic - since we have managed to do so too.

      If someone is interested in redrawing all (currently) verified 994 circuit schematics and having "tagboardeffects.blogspot.com" copyright mentioned on them, we'd be happy to post every single one of those on the layout posts.

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

    ReplyDelete
    Replies
    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

    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.

    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

  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.

  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

  22. So... did anyone else socket their diodes?i did. And then started to notice the led's didnt make a difference. I took some out and nada. No difference. I am still yet to get more volume than unity cranked, who has messed around with the circuit and what results do you have? I am halfway through making a second circuit and will let you know if i have any change. Ive not been having much luck with circuits recently, half and half id say so im thinking i cocked something up. Which isnt a rarity, more and more a common occurance.

    ReplyDelete
    Replies
    1. So i built a second one, and same result. Great tone but no volume, only unity with vol on full. Diodes leds, etc, all socketed and im not having any change to them removed. The only one i can see having an effect led wise is the far left one. Would it be possible to modify the layout to instead of following the schematic that is still not 100% verified, but modifiying this diagram to bring the leds together with doubled up clipping. Would that increase the volume and bringthe leds into the circuit? Is anyone else working on this?
      Also fyi, if anyone wants to make this circuit as is atm my advice is to put a clean boost at the end of the circuit. It would give 2 volumes but dont be worried there are some circuits that have 2 volumes. I did it with a ehx lpb and sounds great, and adds a small amount of tweakability to levels and stuff. I hope this helps with anyone wanting to build this circuit but comes across the same problems until its 100% sorted.

      One last thing. The friedman is a brownsound in a box essentially, i would highly reccomend the handmade hells gain as a great alternative or with a control or two less the bsiab2 that is here. Both excellent pedals.

  23. This is tagged as verified but the comments (particularly Joseph's) suggest it is not working as intended. Who as verified the design? Have they compared to the original? If designs get tagged as verified to easily it calls into question the validity of everything on here. Just my opinion, feel free to ignore.

    ReplyDelete
    Replies
    1. Another complaint? Are we serious? I hope I've got your post wrong but.. Just ignore it? Too easily? The guy that has verified the layout hasn't compare it to the original: Have you? He hasn't got one but he was still willing to try. He has verified plenty and that's good enough for me. Was he wrong? My opinion is that it's not a big deal considering not many people were willing to test it first. How many have you verified? Call into question the validity of what? Vero layouts that some people have ended up selling as their own? IT'S JUST A BLOG and NOT A COMPANY! WE DO THIS FOR FREE! This is a community where people help each other building circuits on stripboard. That's all it is. I'm incredibly busy and don't have much time for myself but I'm still trying to contribute with FREE layouts when I can (have you?). The layout says verified but it's not working properly? Is this annoying you? Tough luck. Of course this is my personal opinion (not the admins or contributors) and I may be completely wrong but that's life. Or maybe I should stop posting layouts and Gavin should stop being the Guinea pig for everybody else. Your call.

    2. sounds like bob just volunteered to buy an original and verify the layout.

    3. Whoa.

      Verified here means that the layout works. We're just depending on the schematics we have. If the trace has errors, it's not layout's fault now is it?

      To put all our work in question is one thing that doesn't get much points here, so fuck you bob. I mean it.

  24. These people need to learn how to read. Schematic is not 100% yet, this layout is what we have to work with and I suggest heading over to FSB and read what is going on with this circuit before building it. I suspect within the next few weeks the folks over at FSB will have this nailed : )

    ReplyDelete
  25. I agree with Bob Smith. The title says that this is the "Friedman BE-OD", and it's tagged as "verified". This is indeed misleading. The layout is working, but as long as the schematic isn't verified, it just can be consider as a circuit similar to the BE-OD. There should be different tags that make that clear.

    ReplyDelete
    Replies
    1. Before attempting a build I read all the comments, read (if applicable) the thread on FSB and obtain any other knowledge I can. Then I can approach the build with confidence or trepidation. Adding more tags on the site won't improve clarity, thats down to the individual. If people can't be bothered to do some research they don'y really have the right to complain IMO.

    3. Misleading? Do you really think I care about that? Has anyone ever paid for the layouts to dare complain? What about no layouts at all? Would that save some people the burden of building a layout they didn't design (cause their lazy or incapable) and complain cause it doesn't work 100% as they expected? Maybe you should buy the original, open it up and share the schematic with everybody else instead of being lazy and wait for someone else to do it. That's kind of what we do with these layouts. This discussion has dragged on long enough. Polite, constructive suggestions or contributions are more then welcome. Complains will be completely ignored (by me at least).

    1. I cannot believe this. Alex, Miro, Zach, IvIark, you guys are incredible. Alex said it succinctly; he doesn't have much time, yet he devotes what little he has to this blog and supplying us with vero layouts.

      It is up to us to educate ourselves as to any particulars with any build. There is nothing misleading here. Just laziness because someone wants a layout handed to them on a silver platter, and oh ya, be sure and personally explain every last detail also.

      Jeez I cannot believe it. 20 minutes of reading and anyone would have all the information needed to decide if they want to handle this build or wait. This makes me sick. The work these guys do for us and you two idiots have the balls to complain?

      I have to tell you I'm disabled, this is how I eek out a living, don't give these guys anymore complaints. I know the work involved in this, it is enormous. I've learned almost everything I needed to know here. Not by complaining, not even by asking questions, they were already asked for me. All I had to do was read. Some of us seriously need these guys and this blog.

      And did either of you realize, I don't remember which one, Alex or Zach, I think, but one of them is attending medical school and still providing layouts for us???? Use your brain!!

      If you don't like it get the hell out of here. There are plenty of other blogs where you can go and complain. Alex, Miro, we love you guys. Thank you so much for what you have given us. There is not enough time in one lifetime to repay you for what you guys have done for us. I swear If I could reach out to these two I would bend them over my knee and educate them regarding manners and appreciation. I still cannot believe this. . . . If either of my 4 adult children acted this way you can bet your last dollar it would be the last time they acted like this when I got done with them. Ever. Adults? Is that what you two are?

      PS: I live in eastern Oregon if either of you two should wish to look me up to discuss this further.

  27. Maybe it would be good practice to mention possible incomplete schematic in these cases. Either on the description text or on the layout notes.

    This might be a thing we could learn and develop our customs from.

  28. i have a buddy that owns one of these .i could probably borrow it or at least snap some pics if need be. What is in question with this circuit ? How can I help if needed.

    ReplyDelete
  29. I suspect a big part of the issues cropping up here is that communicating in type on the net is perilous. It is way too easy to misunderstand another's intent - as I have discovered myself. I can ask a question about something which is then interpreted as an accusation. I never mean to accuse anyone of anything, except delivering information!

    I'm sure that if all you guys met and discussed this stuff you would all be cool. I think Bob Smith has a valid point, but he phrased it very badly, in a way which can indeed come across as disrespectful. And just as I think often any criticism is wrongly directed I also think that sometimes we can be a bit thin-skinned here.

    I am guilty of being thin-skinned in my profession when clients email me their problems. But I have learnt not to email insults back but to call them up, usually to discover they meant no ill-feelings but merely worded their email poorly. Unfortunately we don't have that luxury here.

    Anyway I am extremely grateful for your efforts guys. Sometimes the pedals work, sometimes they don't. Often I have no idea why but I certainly don't blame the strip-board layouts. They didn't cost me anything.

    As an aside, if i find i really like one of the pedals here I ALWAYS make a point of modifying it to suit my particular likes. Thanks to you guys I have learnt how to do that. You should hear the mighty overdrive with separate bass and treble knobs I have made from your BJF Honey Bee board design!

    1. Hey HamishR! I totally agree with you but this is not a profession where you must deal with problems in a certain manner. It's something we do for free in our spare time and life is stressful enough. When you read something like "Why don't you link the schematic?" or "why don't you verify them before you post them?" over and over again cause some people are not bothered to read the circuits introductions, read the discussions or search it themselves, you become thin-skinned. And why shouldn't I? It takes me hours to draw a layout while it takes 1 minute to think and write a polite message. Or just read. You obviously know what DIY means but I don't think everyone understands its meaning.

      Delete
    2. Yup. I also pretty much feel entitled to say fuckyou to badly worded complaints. You know. Spent countless hours on doing something that could be considered as a charity. To call all my work questionable due to one incomplete schematic (not even traced by any of us) - now the complainer will get what he/she deserves. So, for all the whining motherfuckers out there. Please do draw up a few hundred layouts for people to verify from the sources available to anyone. Then wait for the cunts to come and tell you all you do sucks.

      I do take a bit of pride working on my layouts. If someone thinks it's all crap, i do hope that someone would keep it to himself/herself. Again. We're not charging anything for te service. If you can do better, then i suggest you do so and leave all of us out of it. One can always critisize and offer enhancement ideas. Those are welcome. But when the wording comes out as shit, the commenter will be dealt accordingly. By the staff and by most of our regulars. We've seen this happen every single time something similar comes up. Like i've said before, at least 70% of the population on this planet are cunts. Gladly there's only very few of those around here.

    6. Haha! My wife and I agree - most people are stupid. I guess a part of my point above was that, as you say, "when someone behaves like an ass. It's rarely out of malice."

      I freely admit that I simply couldn't do what you guys do. I'm sure I have offended you guys in the past when I really didn't mean to and received some pretty harsh responses! I think we should invent an emoticon for potentially sensitive questions - not a finger or abuse, but maybe a sigh of resignation. Hopefully we would get the point.

      Like others I am sure I misunderstand things I see online. I think it's always a good idea to avoid berating people until you are sure they are a dick. Things are written down, often in short-hand online and can be easily misinterpreted. Sometimes I have simply sought clarity after reading something I don't understand several times and been abused. I hadn't thought I had been offensive but unfortunately without the benefit of tone of voice and facial expression my questions have been interpreted as aggressive when nothing could have been further from the truth.

      Anyway, I think you guys do a great job and should just ignore the dicks. Don't stoop to their level. I'm out.

Makes me think an extra second when I have to deal with patients though. I don't think they would like to be referred to like that, nor should I say "im stoked st the progress you've been making." Lol

  44. Haha, 90's kid here too dude. Est. 1983 and highschool end of the 90's. Im still my hoodies and baggies and im a 33 yr old father now. Hehe. But i build and sell guitars so i hope im the cool dad. Not the dad who looks like a hairy nutter. I think you inject your personality definatly to your patients. Not literally, but it kinda hits home what you said and really recently. My girlfriend could have a serious condition but she was treated by doctors and nurses today that were our age and treated us first and foremostly proffessional to the highest degree (sussex county hospital) but like we were friends and warm and kind. I think one of them let a dude slip today actually haha.

    1. Haha. I just turned 32, hoodies, flannel, and band shirts all the time. Still drive my first car from high school, a 71 chevelle that I've done a massive amount of work on over the years.

      No kids yet, cause I got to finish up school, but yea I figured and figure I'm gonna be the "cool" dad. I tell my wife that when we have kids the only way they can rebel is be super conservative and like pop country. My wife is afraid of what wil happen when they start exploring my cd and record, books, comics, and movies collection.

  46. Alex, thanks for sticking with this one and updating the board – even with all the wack comments in this thread. Much appreciated!

  47. I just plugged it in my test box...oh man, it sounds unbelievable ! Such a great and versatile circuit, I like it much better than my pinnacle deluxe, this will for sure end on my pedalboard.
    Thank you so much guys at fsb and Alex :D

  48. Hi, can anyone guide me where the Out is? It is listed as Level 2 but I can't seem to find anywhere labelled as Level 2. Also where it says Tight 1,2 does it mean that lug 1 goes before the cut and the 2nd after the cut? And regarding the 100k Pot on the board, what is that for?

    1. 1. There are three terminals on the volume pot. Output wire connects to volume pot's lug 2. Alas, "Volume 2 to output".

      2. Tight, no. The one wire coming from hole labelled "Tight 1,2" connects to tight pot's terminals one and two.

      3. The trimmer sets the gain for the presence, treble and hard clipping shunt diodes. This could be adjusted to taste.

    2. Thanks a lot for your helpful reply! Would you recommend to leave the trimmer on the board or off the board?

  49. Does it matter 3mm or 5mm leds?

  50. Just finished building it and it fired up first time! Didn't have any reverse log pots, so just used the linear equivalents, and it sounds fantastic. Colossal thanks to Alex for another top job, and to absolutely everyone who contributed to getting this bad boy verified and working. Top effort guys!

  51. It worked very well with the pedal open, but when I boxed it stopped working. It seems the tight pot is bad. I'll change tomorrow. But apparently, everything works perfectly. The trimmer makes a lot of difference in noise, treble and amount of gain. Next time I'll leave it outside. Next week I'm going to record a video and post it here.

  54. Im sorry if this is addressed elsewhere, I may have missed it. What side of the l.e.d. is marked on the layout?

    1. You don't mind the side, you just have to solder them upside down on each pair (one side of the led is flat)

  56. I boxed mine and it suffers from a strong high pitch whistle with the gain passed half (it was not that bad with the circuit out of the box). I see 3 solutions:
    - Shielding the input (from my experience it sould not help that much)
    - Add a buffer before or after (it helped a lot with the sevethheaven)
    - A guys at fsb replaced the 120p by 470 and according to him that made the trick, so I will try that also.

    2. hey that's really a smart way to do a stripboard. did you clue the printout to the board?

      Delete
    3. Thanks yes I always do it that way, print it an a sticker sheet and stick it to the board. You can't misplace a component that way

  57. BTW, I solved the squealing problem by plugging a Klon buffer in front. Now it's dead silent even with all the settings maxed
