Just wanted to share my ditto on the great sound of the BBOD kit. I had no issues at all with the build, although I may have mixed up the capacitors (or what that the Octave Fuzz..) but by laying out the parts ahead of time and using the code numbers I am getting better at divining which cap is who.
The one things that not all instructions have is a picture with the components in place. This really speaks to the caps mixups, but it is kind of nice to have a quick visual check.
Another nice check would be a diagram of where to take readings to learn to troubleshoot. I found one of these posted for the Confidence Booster. But then by using the schematic I should be able to figure that out, which is probably a better way to learn, so never mind. I haven't made a mistake yet to try to troubleshoot, but I don't think that will last.
