The Aclam Dr Robert creates an accurate replica of the iconic Vox UL730 amp made famous by The Beatles on their Revolver & Sgt Pepper albums.  This classic amp was also used by The Rolling Stones, Jimmy Page, the Joy Division and so many more.


Only 100 units of this legendary amp were produced, and most of them were destroyed.


As a special touch, Revolver's album cover designer, Klaus Voormann, created the artwork for Aclam's Dr Robert pedal. 




This amp-in-a-box pedal was designed to be the closest replica of the Vox UL730 amp’s soul and character.  A meticulous process of tracing the original tag board circuits and measuring each component’s value has resulted in a sonic approach never reached before.

✔ The most accurate replica of the original UL730 preamp

✔ Aclam Smart Track® Fastening System
