EEK!
I am a hifi guy. I hate distortion if it is produced by clipping or class-B crossover, even harmonic or odd harmonics. You are even cutting low frequencies which makes the distortion sound louder and you have an awful output transformer that mutes high and low frequencies and has its own distortion. Your circuit does not even have any overall negative feedback so the distortion is all over the place. A buzzer is not a musical instrument.
Ban acid rock and bring out the pleasant sounding acoustic guitars, played through a modern amplifier design that has a wide bandwidth and distortion so low that it cannot be heard and is very difficult to measure.
