The circuits in my Weird Noise Synthesizer were interfering with each other, so I decided to remove the Swanee Whistler and the Relay circuit and put them in separate jars!

Triple-Chip Frantone Peach Fuzz
I'm a Fran fan!
I had got a Frantone Brooklyn and a Thunderhead relatively inexpensively, but you don't see any on eBay for under £300 nowadays! You can get the twin-LM386 chip Peach Fuzz as a kit, but I wondered what would happen if you made it a triple-LM386 chip circuit.
So I prototyped it on breadboard, did some sound samples, and analysed it on Audacity.
The third chip does make the waveform more ragged, and the spectrogram shows that it's more trebly, which does mean more fuzz! It also has so much sustain, you can go and make a cup of tea whilst it decays!
Also, the stock Peach Fuzz tone control has a really big range.
So I might build it as a proper pedal in the future.
