Found this site with a few schems, but they are all from the service notes, so they have reference designators, HMS, MT2, FW3 wansn't someone looking for the FW3 schems a while back...Dr.Bob? http://nicosonic.free.fr/schems/ |

Hi Christo Thanks for the link. If you go back to tha main page. He has some interesting other stuff on the site as well. If you click on the English flag, you won't have to try & translate.
Did you see his (1) resistor tone-gain mod(fix) for his OD-1?
Regards Dr. Bob  |

Thanks for showing the other pages, was looking up other stuff and didn't get a chance to check out the rest of his site. Yeah, did see the one resistor mod for the OD1, changes a low pass filter from 884hz to 402hz, might try it w/ a switch. I can see that giving a bunch of low mid/bass. Indy mentions that location on a SD1 to give it more gain/drive, but the removal of C6 is usually included.
His FZ3 mod looks interesting, removes a buffer before the fuzz, and upgrades the transistors to 2N3904. I even have some real'5117' transistors to give it that real mojo. Even tho other's research shows that the 5117 is a manufacture's part number, and equates to the 2N3904 used at the time. |

Here's the DD-5 Digital Delay schematic, which was floating around these forums: http://us.share.geocities.com/glowgloves/dd5.jpg
I will be taking mine apart soon, so I'll post links to photos of the parts missing from the schematic, and maybe someone can reconstruct what's not there. Else, it'll be good for reference, anyway.
EDIT: I got the picture: http://img299.imageshack.us/my.php?image=img2215qw8.jpg pots are, left to right: Mode: 50K, B (linear?) Delay time: 50K, B Feedback: 50K, B Effect level: 10K, B
It looks like the VR board is very similar to the DD2: http://experimentalistsanonymous.com/diy/Schematics/Delay%20Echo%20and%20Samplers/BOSS%20DD-2.png |
