scaffolded common base fuzz

Jan 30, 2025 4:56 PM

modded bazz fuss... if you can even believe that. it started with replacing the collector resistance with the virtual base resistance of the PNP voltage follower up top. then i decided to make it common base by switching which connection goes to ground or gets the signal, so to facilitate the low input impedance of a common base amp, i added another direct coupled PNP emitter follower. That one has to be a Darlington for more input headroom and to keep the input impedance in check. common base has softer clipping characteristics compared to common emitter amplifiers.

Any reason why the input filter is about 7Hz cornering frequency?
