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.

Worked for two years only

The pedal worked for two years with very little use. It now produces a thumping noise. Not usable at all. No response from Aclam to my inquiry. The website says: lifetime warranty.

Thank you for bringing this to our attention, and apologies for the inconveniences. We are reaching out to you directly to resolve the issue as quickly as possible and ensure it is properly taken care of under our lifetime warranty.

Dr Robert

A faithful replication of the Vox amps The Beatles used on Revolver and Sgt Peppers. An excellent overdrive effect pedal in it’s own right and a must for anyone chasing Beatles tones.

At Last the Sound

Ever since I watched the Beatles on the Sullivan Show I was hooked. I've played guitar for many years and tried many products but not until I purchased and heard the "Dr, Roberts v3" did I get the sound that I was chasing. The pedal is amazing, and the amp simulation is spot on. It is definitely worth the money, really, go get one!
