The Dr. Robert pedal stands as the most precise reproduction of the legendary VOX UL730 amplifier, renowned for its use by The Beatles on their Revolver and Sgt. Pepper's albums. It has also been favored by artists like The Rolling Stones, Jimmy Page, and Joy Division. With only 100 units of this amplifier ever manufactured, the majority have been lost to time. The artwork for the Dr. Robert pedal was crafted by Klaus Voormann, the designer behind the Revolver album cover.
