New Build Doc: "Build Your Own DS-1 Distortion"

[DiamondDog]

Great work, Brett and Miqbal!

Thanks.

Can I make one suggestion regarding the 'straight' DS-1 layout, though. The way it is set up at the moment, you have to heat up a pretty substantial area of the gound poor to solder effectively, and when you do it's a messy result. If your design program allows it, it is easier if you have a solder pad in and isolated from the pour, which is then connected to that pour. Confused?

Well, a little confused.  When you refer to the 'straight' DS-1 layout, are you referring to the Stock DS-1 layout or the True-Bypass layout?  Muhammad designed the Stock DS-1 schematic and layout on Eagle CAD.  I did the True-Bypass DS-1 schematic and layout using Microsoft Visio 2007.

The traces in the Stock DS-1 layout are, on average, bigger than those on the True-Bypass DS-1 layout.  Muhammad tried to match the trace shape and size of the original BOSS traces as possible.  (You can reference a solder-side image of the BOSS PCB here: http://i76.photobucket.com/albums/j23/overdrivespider/step03_05.jpg.)  One possible solution to excessive solder flow would be to apply a solder mask, as BOSS did with similar-sized traces on the post-1994 DS-1.

Sorry, "Stock" was the word I was lookign for, not "straight". I get confused at my age. Too many things in the 70s. No, I 'm not joking.

Muhammed mentioned somewhere else here on a DS-1 thread that he was having a bit of an issue with the soldering, and this could be why. It's not a matter of solder flow- it's a matter of trying to heat up the whole ground pour area.

If he's happy, then that's cool. Just thought I'd mention it.

Howdy, everyone!

I added a new mod to the 'Build Your Own DS-1 Distortion' doc.  It's called the VR-MIJ.  You can read about it when you download the latest version of the doc: http://www.diystompboxes.com/DIYFiles/up/Build_Your_Own_DS-1_Distortion.pdf.

Here's the introductory text for the VR-MIJ:

"This mod started with Jack Orman's "Fat mod for the Boss DS-1" article. My initial tests with this mod resulted in an increase in perceived bass and mid frequencies, due to the cut in treble boost from this mod. I wasn't happy with it at first, as it reminded me of a fuzz pedal, which wasn't on my pedal "to do" list at the time.

So after thinking about it more over the next day, I wanted to try combining the Mondo-MIJ mods (minus the clipping network), Jack's "Fat mod" and MOSFET clippers in an attempt to increase the note articulation and cut the fuzz-like qualities of the pedal. I was VERY pleased with the result, which is why I'm presenting it to you here. Please meet the "VR-MIJ" Mod. (The "VR" stands for "Vintage Ripper", while "MIJ" shows that it's still part of the MIJ-Mod family in terms of other component replacements.)"

Thanks, I'm glad you like it.  Muhammad got the ball rolling by creating that exquisite stock DS-1 schematic and layout.  I got inspired by his work and did the true-bypass schem and layout.  Everything else came along in bits and pieces after that initial inspired outburst.

Hey there. I'm thinking to build one too, TRUE-BYPASS DS-1 DISTORTION one, with mods. But original author email not exist already... And in pdf is picture of layout, while i need a layout file, to order pcb... Maybe anybody have one? Ty
