The 100uF -ve lead needs to go to ROW A instead of ROW D (e.g. after the 100R) to stop the oscillation! Was a good troubleshooting lesson to have a go at reversing layout to schematic, and then comparing to original.Nath Shttps://www.blogger.com/profile/08551201716780267914noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-60301425526096054962019-10-19T04:20:56.351+01:002019-10-19T04:20:56.351+01:00Hi yves, just tried this one myself and hit the sa...Hi yves, just tried this one myself and hit the same problem past 25% on fuzz.

With the fuzz pot turned all the way down, the circuit sounds great. A smooth warm drive/fuzz. But as I increase the amount of fuzz, I get oscillation. It starts oscillating once I turn up the fuzz past say 25%. Any ideas? Is this a bias issue? Love to get some insight into how to troubleshoot this one.
