HOW TO ADJUST THE SYMMETRY
The symmetry control lets you smoothly adjust
the symmetry of the waveform that controls the
bulb brightness. Turning the control below the
halfway mark making the wave more pulse-like
which is great for ‘throb” type tones. Moving
the control above halfway gives you a long
slow wave which only briefly dips, this produc-
es a very smooth and chewy vibe effect.
Hold the ‘Channel’ Foot-Switch, make the
adjustment to Symmetry or/and Bulb, release
the Foot-Switch. To retain the setting, press
the bypass Foot-Switch.
BULB and SYMMETRY controls
Vibe guitar pedals use a bulb to control the photocells which in turn effects the speed and depth of the vibe. The
way the bulb is set has a strong influence on the type of tone the vibe produces. This is one of the reasons Vibe
pedals all sound different. The Vibe-1968 has a ‘Bulb’ control on the front panel, this allows you to dial in an exact
bulb setting, shifting the overall type of tone of the Vibe-1968. Furthermore the Bulb setting for side A and B can
be set independently, so you can shift from a classic throb or chewy type vibe tone to an almost wah-like or even
rotary speaker sounds just by switching channels.
