a tinny update, as said in previous post I want a LFO which can go into audio range without multiple switches (or at least one) to keep it simple.
it doesn’t really go deep in the audio range (but can if you don’t mind the crappy waveform, just remove C3/C2 and let the internal capacitance do the job) but it may suffice for such dirty-grungy noise machine.
However, I’m not really happy with the output waveform which looks more like the usual charge/discharge cap waveform you get from such circuit. Not pretty, or not enough. I may try to find another one shortly. But it could do the job without doubts !
