The only reason SE amps have even harmonic distortion components is because the even harmonics are not cancelled out by the circuit topology. All other amps are differential and the even harmonics are naturally cancelled out by again the circuit topology through the load. The sinusoidal waveforms sent out from instruments have both even and odd harmonics inherently.
