Dr. Robert is based on a real VOX UL730 S/N 3042. The rare amp behind some of the tones heard on Revolver & Sgt. Pepper’s. Only 100 units of this amp were produced and most of them were destroyed. This is the closest you can get to the amp!

You’ll pay money just to see yourself with…

Awesome pedal, so versatile especially with the new EQ knobs, I had the first version and this V3 is a great upgrade. From subtle clean to heavy distortion, and everything in between. Great for recreating beatles tones but also great on any pedalboard to add more possibilities. Fully recommended

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!
