The Tube Drive module adds subtle even order distortion after the compression processing, simulating the effect of a vacuum tube amplifier. This provides a difference in the sonic signature of TL Aggro and is most noticeable on audio with harmonic content such as piano and acoustic guitar.
To engage the Tube Drive, turn the Tube Drive rocker switch to on by clicking it. The Tube Drive rocker switch and tube light up when Tube Drive processing is on. The amount of distortion increases with the output level.
