Redirected from Tube sound
Transistor amplifiers or DSP algorithms can approximate a valve sound by adding square law distortion, approximating the effect of the triode characteristic of the original valve amplifiers. Adding a slight DC bias before the distortion results in even harmonics that make the sound somewhat more pleasant.
"Valve amplifier" is an English expression for what Americans call a "tube amplifier".
