Earthquaker Hummingbird V4 Tremolo Effect Pedal - UsedA JFET based vibrato pedal for the masses! Similar to the tremolo circuits in vintage Vox and Valco amplifiers, the Hummingird handles everything from classic shimmering tremolo to a synthy fast chop. The V4 model features a relay based, true bypass switching style allowing you to simultaneously use momentary and latching style switching. This pedal is in very good condition, with some light visible wear on the chassis.
