Brian Wampler, President of Wampler Pedals demonstrates his Nirvana chorus/vibrato pedal with the help of guitarist Steve Townsend. You can select from three switchable intensity levels to create your perfect chorus, most pedals don’t give you control over this. Couple this with independent depth and rate controls and you can dial in the exact effect you’re looking for. Flip a switch and turn on the vibrato effect. This is great for slight to far out, trippy tonal variations. Enjoy the demo, then check out the Nirvana chorus/vibrato in detail at the link above.
