Tube

The Tube is a tube amplifier simulator based on "soft clipping". An overdriven tube
amplifier sounds good because it generates even harmonic distortion products. This
digital tube gently rounds the waveform in a smooth, controlled manner much like a
real vacuum tube. Set the amount of distortion using the Gain control, then adjust the
tone using the Treble and Bias controls. The Compression control smooths out volume
changes and the Output Level control sets the final volume of the effect.
In
Parameter Description
Gain This parameter controls the overdrive amount on the "tube" and
thus, the amount of distortion generated. Range: 0.25 - 50.00
Output Level This parameter sets the output volume level and has no effect on
the tone.
Presence This control sets the lowpass filter frequency at the output of the
"tube".
Compression Tubes have a certain amount of natural "soft" compression. This
controls how much compression is applied.
Bias Bias controls at what point in the waveform clipping begins.
