TUBE

Tube rounds sharp peaks and adds harmonics that can make a thin voice, piano or guitar feel fuller. Use it for a little warmth, or push it until the recording has an audible edge.

Adds more saturation as you turn it up, rounding attacks and making the sound denser. Back it off if consonants, piano strikes or picked notes lose their shape.

Negative settings add body and soften the top; positive settings lighten the bottom and brighten the top. Use it to keep the warmth from turning muddy, or to ease a sharp edge.

Blends the tube sound with the original recording. Lower it when you want warmth but need to keep the original attack and clarity.

Changes the kind of harmonics Tube adds, with higher settings bringing more of a soft octave above the notes. It is a change of character rather than another drive control, so compare it on a held note.

Turns the processed sound up or down before it blends with the original. Use it to balance the effect against the bypassed recording so extra loudness does not decide for you.

For a thin vocal, try DRIVE at +7dB, TONE at -1.0dB, MIX at 70%, BIAS at 40% and OUTPUT at 0.0dB. Listen for a fuller voice with clear words; if it becomes woolly, bring TONE toward 0.0dB or reduce MIX.
