Unfort...Hey to you and others trying to build this. Unfortunately this layout has some errors. One is mentioned above, that the 68k resistors that go to pins 14 and 13 on the UAF must be switched around. <br />The other is that the wiring for the Fuzz Wave toggle switch isn't completely explained. Pin 5 of the switch goes to lug 2 of the Fuzz Vol pot and pin 3 is connected to pin 6. Also you will have a lot of whine-oscillation from the MAX1044 chip if you don't bridge pins 1 and 8. <br />Other than that the layout is a good base to build on if you follow the schematics that are available on FSB and do these modifications. Good luck!s0b9rhttps://www.blogger.com/profile/05802713587958418146noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-18716421126251467562021-05-24T19:36:17.437-04:002021-05-24T19:36:17.437-04:00Is this change reflected in the latest image on th...Is this change reflected in the latest image on the post?

Just found it in my drawer of non-working circuits, thought I should put a little update here. Unfortunately, it's not working (no sound when engaged and bad pops when it's turned on/off). Is there a way to upload a photo here? Maybe if someone sees an error, I can try fixing it so this layout could maybe get verified. I would love to get it working rather than stripping it for parts.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-4803288663716695872016-05-18T10:13:41.439-04:002016-05-18T10:13:41.439-04:00Yeah, this was an unreleased version.
