Dr Robert Pedal is the most accurate replica of the iconic VOX UL730 amp. Made famous by The Beatles as they used it on Revolver & Sgt. Pepper's albums. Also used by The Rolling Stones, Jimmy Page or Joy Division... Only 100 units of this amp were produced, and most of them were destroyed. Klaus Voormann (Revolver's cover album designer) has created the artwork for the Dr Robert pedal. In late 2025, we upgraded the Dr Robert by adding external controls for the Bass/Treble EQ and the Mach Schau! Gain. On top of that, the new global Lo/Hi Gain mode makes the pedal more versatile than ever.
