Handmades Hell's Gain / HG-1

This was a request.
It's a diy Marshall emulator designed on Handmades Brasil forum.
You can find the original schematic here.

  1. Thanks Alex. Will give it a go at the weekend.

  2. can I sub the 1n4007 for another diode I don't have any on hand, I have all my resistors laid down once I get a response I do the diodes and caps and hopefully verify later tonight. Thanks alex also I have a schematic for the none more black version one, one of the rare 18v versions in mxr size if youd like to give it a build and possibly make a layout let me know. it uses j202's and is almost similar to a slo 100 but its not even that original for sure

    1. You can use any diode you want there. It's a clipping diode so many other types will function and sound very close to the same. Do you have other 1n400x, like 1n4004 perhaps or 1. Uses those. Otherwise use two more of the 1n5817's. Or 1n914's

    1. Cool Jesse!
      I've just seen the Menatone None More Black schematic.
      Do you have the final correct version?
      Any chance you have it black on white and larger?
      Can't read the components values.

    2. It looks like there is a ton of good information especially on the pdf download. But I don't, and probably most of us here, don't speak or read Portuguese.
      I wish I did, but ...
      And ... I'm certainly not complaining.
      Glad we have it because I really appreciate the schematic(s) that Alex (& the rest of the crew) posts or directs us to with his/their layouts.
      Maybe someone could translate some of the more important parts and put that in the comments.
      I know that's got to be some hard work, but I do speak German ...
      maybe a trade, if you have something important that the Google translator has f'd up with ???
      Just a thought ...
      Thanks guys, for everything!!!
      Will

  5. Send me a email Alex as I only have it in PDF and I'm pulling my hair out trying to figure out how I can post it here for everyone to see because it won't let me paste anything in this comment box. Instead of giving me the option it just says look up

  6. theres new comments that explain everything and when I get your email ill send you the pdf I have however it will need to be updated because of a few small errors like the 1uf and 1,8k cap, there actually in parallel and etc the post will give you all the info you need as one of the member worked out all the kinks and pposted comments on how to fix it in the post

    1. There's a corrected PDF on the FSB link.
      Is that the one?
      I've sent you an email.

  7. I have a Portugese work colleague who is translating the PDF for me. I'll post it as soon as she is done.

  8. i've got a short on my board, the 1n5817 and the voltage converter are overheating the second I figure out where my short is coming from ill wire it up.Im trying as hard as I can to get this verified:)

  9. Is it just me, or does that demo make this thing sound more Marshally then a lot of more... commercial products?

  10. Ok PDF translation turned out to just be how to populate the PCB board and the types of jacks to buy etc. No real information on the circuit apart from this little bit at the beginning "The pedal herein described has diverse characteristics that will make the guitarist very happy: moderate to high gain, detailed and acting equalization, high exit capacity, allowing it to be used at setup as a distortioner and booster at the same time; plenty of buttons (most really like buttons); Marshall distortion model; compact; etc."
    Also they added this "The circuit herein presented is of the authorship of Haroldo Gamal and is part of the collection of projects of the forum handmades.com.br, with no restrictions about its commercial or private use."

  11. How is the status LED connected? Negative to the 3PDT and the positive only to the board?
    Or the positive from the board has to go also to the power supply? Thanks..

    1. Thank you everyone that worked on the translating and making available the information in the pdf file.
      I'm sorry it took me so long to comment back but because of weather I've had no internet connection for the last few days.
      This is a perfect example of what a great community we have and how terrific & informative this blog really is.
      I'm sure that I'm only one of very many that have learned & benefited a great deal by reading & participating in the products of this great web site.

    2. I forgot to mention a big thank you to Gavin also ...

  13. Verified! This is a brilliant pedal and sounds very similar to the YT vid. Definitely worth a build IMO. Hats off to the guys at the Handmades Brasil forum, they really have created a masterpiece with this one. Thanks Alex!

  14. I agree with the comment above about this sounding more marshally than other boxes. Don´t know what model is, as I have little experience with marshalls, but this thing does the hair metal thing in spades...
    Contour controls the mid frequency, right? Or is more of a presence control?

  15. Brazilian here... I skimmed through 29 pages of discussion about this circuit on the Handmades Brasil forum and there's nothing of interest, just the regular questions about what IC alternatives to use, how to buy the pcb, how great the circuit sounds etc, so don't waste your time trying to translate that and go build it :)
