The Big Brother to the VB1, using the same “vibrato” circuit, we have two stages of vibrato.
Each vibrato stage has its own LFO and DEPTH control, or you can sync the stage 2 LFO to the stage 1 LFO in or out of phase, and add some of the dry input signal in.
The range of controls allows for even more extreme vibrato than the VB1, or two different vibrato speeds and depths at the same time for glorious wobbliness that you cant get in any other pedal.
