We've got a few of these incredibly versatile tremolos in stock and for sale. From classic tremolo sounds to more intense/experimental ones this pedal can cover a lot of ground! The shape knob varies how evenly the volume changes occur and when used in stereo you can vary the phase between channels with the ch. phase knob to create more intense width. Another great feature is its LED indicator light which flashes in time even when the pedal is off so you can time the switching appropriately. These are NOS (new old stock) pedals with original packaging and the manufacturer warranty as we are proud Seymour Duncan dealers. As an added bonus we're including a t-shirt (please let us know what size you would like) and some extra swag ($30 value) just because of how great this pedal is!
