Arsenio Novo - Tube Sound Overdrive
It is easy to see why?
Here is Arsenios explanation:
The operation of the circuit more closely resembles a vacuum tube than a diode clipper does because of the strong square law characteristic. This is due to the negative feedback around both base-emitter pairs. This feedback accentuates the junction non-linear behaviour manyfold. Thus each transitor drives the other even harder so that the transfer curve ends up more logarithmic than is typical of a single transistor. In other words: the clipping is gradual and not abrupt like it is in the case of a silicon diode. Typically a lot more 2nd harmonic is produced as well. As a bonus the waveform folds over on itself when the circuit is overdriven!
