This is not a family-friendly overdrive pedal, despite its glorious, singing Beatles-esque tones. Aclam have modelled the Dr. Robert after the rare Vox UL730 solid-state preamp, made famous by The Beatles, as well as other monumental names like Led Zeppelin and the Rolling Stones.
You'd be right in thinking the artwork looks familiar - Klaus Voorman is the man responsible, who designed the cover for Revolver. It's the 21st century and you still can't escape Beatlemania.
Based on the Vox's Normal channel, the Dr. Robert is an uncanny replica of the original used on two legendary albums; Revolver and Sgt. Pepper's Lonely Hearts Club Band. It was the true secret weapon of their guitar tones. If any pedal is likely to whip up a Beatles' fan frenzy, this is it.
Only a small number of UL730 amps have survived to the present day, so you'll be getting your hands on an extremely exclusive sound. The Dr. Robert captures the essence of one of the first hybrid amps ever created. It sounds great either through guitar or bass, cancelling out low-end drops.
Featuring Volume, Gain and Middle controls, the latter is the key to producing both scooped British tone when rolled off and unprecedented saturation cranked high. It's only accentuated by supreme Alpha pots and switches, and the finest Wima caps.
Aclam have added their own Mach Schau! custom FET circuit to the mix just for good measure. This mimics the feel of the tube power amp section, saturating things even further and makes for a great lead tone. Adjust using the independent Volume control.
As with all Aclam pedals, the Dr. Robert features a custom enclosure with side thumb screws to fasten the pedal to Aclam pedalboards and select boards from other brands.
