VHT V-Drive Pedal - Manual (Page 5)

DRIVE
The Drive control adjusts the signal level that drives the clip-
ping diodes, and thus the amount of clipping and the level of
the clipping threshold. Working in conjunction with the Select
and Texture controls, these three controls offer an incredibly
wide range of overdrive choices.
TONE
The V-Drive’s Tone knob is voiced higher than most overdrive
pedals. Unlike most overdrive pedals, it adjusts the treble
content without altering the midrange. The V-Drive’s Tone
control works in conjunction with the Depth control to provide a
wider EQ-shaping range than conventional 1-knob tone-control
overdrives.
VOLUME
The Volume control adjusts the V-Drive’s output level; higher
Volume control settings can be used to overdrive your ampli-
fier’s preamp.
