Product description

What makes Dr. Robert pedal so special?

- The Dr. Robert 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.

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

- Klaus Voormann has created the artwork for the Dr. Robert pedal. 

It has not been easy to get here. If you are curious about why and how we got here, we strongly recommend you watching the full series of videos in our Youtube channel talking about all secrets behind the Dr. Robert effect pedal.


Dr. Robert pedal main features

  • Replica of the VOX UL730 S/N: 3042

We’ve found some internet and old schematics but major discrepancies between the published schematic and the real thing were detected. We checked every component type and value so we are 100% sure this is the closest you can get to the rarest Vox amp.

The pedal also works with the same voltage the original amp does, the circuit takes the 9VDC and converts it to 18VDC.

  • Mach Schau! (extra feature)

Get more saturation with an independent volume control. Use it in solo parts to raise the volume or just to have more distortion with the same volume.

"Mach Schau!" was shouted by the businessman from one the Hamburg's venues when The Beatles resided in Hamburg when energy fell flat, and they had to put on more of a show.

  • Dr. Robert works for guitar & bass players

The VOX UL400 series (designed for bass) almost have the same circuitry than the VOX UL730 preamp.

We tunned the FET circuit so Dr. Robert sounds flawless with bass too. No low-end drops resulting in a great preamp and distortion tool to plug directly to the desk or into an amp.

  • High end components and true bypass switching

You will find the finest and closest components to the original amp on the Dr. Robert: Carbon comp resistors, Nichicon Fine Gold and Wima caps, Alpha pots and switches...

  • Bass and Treble internal controls

The original VOX UL730 had a 3 band eq: Middle, Bass and Treble.

Middle control is the one that helps to tailor the tone better, that is why this is one of the main controls. You can access to Bass and Treble controls inside the pedal.

  • Artwork made by Klaus Voormann

Klaus Voorman, designer of The Beatle’s Revolver album cover sign the artwork for the Dr. Robert.

  • Take advantage of the Smart Fastening System

Our pedals use a custom enclosure designed to match perfectly our Smart Track® pedalboards. Using the side thumb screws you will attach and lock the pedal into the pedalboard, with no risk to loose it or to get robbed easily.

It also comes with a high quality Velcro® pad so you can use it on any other pedalboard in the market.

Must own pedal!

I bought the pedal through online store. Customer service is very responsive and friendly. The delivery via Fedex was faster than expected. I played with the pedal non-stop after receiving. It is a faithful recreation for the tone as promised by Aclam Guitar. Well done and a must own pedal for any fans!

exceptionally good distortion pedal

Sure, there is the direct Beatles influence in designing this pedal, which is part of what made me get it, but there is really much more.

Ive always loved those sounds on Revolver and Sargent Peppers and never knew what was going on for the fab four to be able to get their guitars to sound like that. Now i do and i have a pedal that goes a sincere way to getting mine to sound like it too.

Really though, for me, this is just a great distortion. I have enough screamers and overdrivers that do so well what that tradition of effect wants to achieve, but it also gets boring, and many alternatives can be exciting within a small range and then its just too much or plainly mud. The Dr Robert doesn't suffer from that in the same way. There a much wider range of sound and possibility outside of the usual screamer domain that i'm falling deeper into use with it every day.

When i first got it, all i could think about was Beatles sounds and grooves, but now i;m over that and using the pedal as my own sound treatment, stacking it with my other pedals and playing anything i like. I actually havnt thought about the Beatles in regard to the pedal for a while....... im just making music and i really appreciate this pedal for what it does within that.

It seems like a lot of money for a distortion pedal but it offers something different and it's very well made. You have to remove the back to access the battery compartment, which is time-consuming, but you get to see the very neatly assembled circuitry. The sound is crunchy and refreshingly retro, a bit like a TS9 with the tone control on max, but with even more attack. This pedal isn't "polite" - it's raw and aggressive and rock and roll and I like it!

Special pedal

It’s rare that I buy a pedal that gets more than occasional usage. Especially overdrives. This one, however, is So good it could be constantly engaged. With the eq function it is really versatile

Very satisfied

I’m giving this product a five out of five.
The sounds are extremely authentic and paired with the right pick ups it’s dead on perfect.
The packaging is fantastic and the box comes with beautiful touches and a special pouch also drawn by Klaus V.
