Best 60’s British Invasion Pedal!

The Dr. Robert does indeed recreate that very rare 60’s Vox tone of its curious solid state preamplifier.
It also is very educational on many 60’s U.K. recordings where that Vox was used but never discussed.
I LOVE my Dr. Robert pedal and the incredible research of Aclam to make this happen!

not only for Beatlemania

My first gear from Aclam Guitars.
It is more versatile than I expected. It goes very well with many other pedals like tone bender style fuzz or Klon style overdrive and more.

Awesome!

This isn't just a simulation of "Revolver" guitar tones. It's a great overdrive and boost in its own right. Stacks great with other drive pedals. Mach Schau!

Dr. Robert

Review! Order Reference DMEOKTDSI
Thanks for a outstanding SUPER good high quality Beatles Vox amp sounding pedal.
This is the 2nd Dr. Robert I purchase directly from you.
The pedal sound fantastic, whether it's connected through a transistor amp or though an amp with tubes. I’d play the Dr. Robert though a transistor amp for approximately 6 years, great responding and sounding Dr. Robert no doubt about that. Recently I’ve been using an AC30 TBX with the pedal, which gave the Dr. Robert even more life and character. I’m very satisfied with the purchase of the pedal, and I’ve even recommended it to my band member, who went out and bought one immediately after.
We have a Beatles tribute band, called The BTLS (located here in Denmark), and the Dr. Robert pedal really and honestly brings the period from 1966, forward sound wise.

Thanks for your products, dear guys at Aclam

Take A Drink From His Special Cup

I just got my Dr. Robert pedal a few days ago, so I haven't had a chance to really do a deep dive with all my various guitars and amps, but so far I'm very impressed with what it can do. Having the extra Mach Schau button is brillant, as it allows you to kick it up without needing a second pedal.

There are lots of options with this box, especially when you play around with the MIDS and GAIN. I can't wait to run it through my Vox AC30, Cambridge Reverb, and Berkeley Super Reverb amps using my SG and Epiphone Casin. So far I've only had a chance to use it with my SG through a Marshall practice amp, but it sounds spot on.

I'm trying to track down one of The Mocker pedals to go with it, as the demos I've seen sound amazing. I've heard there's a chance it might be reissued later this month, so finger crossed. AT any rate you should pick up one of these if you love that mid- to late-60s sound.

The best pedal I own

It allows me to recreate Harrison’s solos all the way to Let It Be. Widest variety of sound can be dialed in. I enjoy luscious distortion sound of pure Rock’n’Roll. Amazing pedal. You will not regret buying it!

Dr Robert

Wow, someone call a doctor as I feel like a Beatle. Seriously though, this is an excellent sounding guitar pedal. I’m using both a semi-hollow Gretsch and a Reverend Double Agent and the sound still sound Beatle-esc. My guitars now punch through in the mix and the sound inspires some mean song writing.

My Mind is Truly Blown

I am a walking contradiction on pedals, I try not use them but typically end up using 4-5 different ones (a Klon clone, a TS clone, a Rat clone, an Angry Charlie, and a compressor). The Dr. Robert pedal has changed, forever, my world view of guitar pedals. For starters, all my other pedals are now put away. My guitar is now plugged into my Boss tuner pedal and then runs to Dr. Robert, and the Dr. directly to my Twin Reverb. The tones out of the good Dr. are amazing, at all settings of the mid and gain. It is truly beyond my comprehension, it defies logic how no other gain, overdrive, or distortion pedal in my last 30 years of playing has never been close to this level of performance. If you need a sample, go to whatever music service you subscribe to and check out a song called What Would You Do by The Sad Mall. It’s literally the first thing I recorded the first day I received the Dr. Robert pedal. All the guitar, rhythm and lead, is Dr. Robert. It’s a special piece for sure and it is NOT niche in my opinion. That circuit (UL730) is epic and special. I couldn’t be more satisfied with the purchase. What Aclam does is without peers and I am scoping out the next purchase of another pedal of theirs. Keep up this work, we need exactly these kind of products.

A Truly Fab Pedal!

For anyone in search of that authentic Beatles '66 sound, this pedal is fantastic! I am very thankful for this, and for all the hard work and effort that went into making it the right way. The Klaus Voormann illustration is just the icing on the cake.

Fantastic tones.

If you play Beatles music this pedal is a must have. The sounds are spot on and you can’t get them anywhere else. I don’t know how the aclam engineers and designers do it but this pedal is magic.

An unexpected surprise

Finding the right guitar tone to recreate the magic the Beatles managed to achieve in the studio, with the help of George Martin and Geoff Emerick, particularly on albums like Revolver and Sgt. Pepper has never been easy. Thanks to this little masterpiece born from the passion of Marcel and Marc of Aclam, I found myself having a VOX UL730 at home and I discovered that the real heart of those sounds was in the amplifiers they were using. Thank you guys for this wonderful surprise and for giving me the possibility to add the right color to the sound that I have had in mind for a long time. ????????

Just What the Doctor Ordered

This pedal produced insanely useful tones with great ease. The mids knob can really influence the way my guitars break up in a way that other distortions I've tried do not. The user manual is very informative. The pedal is built like a tank. And the Klaus Voormann artwork is the perfect final touch. Well well well, he'll make you: Dr Robert.

Rhythm Guitarist for The Raves

Dr. Robert pedal from Aclam guitars

Let me start by saying I am not a gear head or pedal junkie. But ever since I heard this pedal a couple of years ago I wanted one... and I love it.
Vox amp lovers know the company missed the boat when it came to giving them the sound from their mid sixties groundbreaking hybrid UL700 series of amps. They were originally made for an exclusive clientele including the Beatles and The Rolling Stones, and only 20 or 30 are know be in existence today in the hands of collectors willing to pay exorbitant prices. Luckily the folks at Aclam guitars in Barcelona, Spain managed to buy a UL730 and reverse engineer the main channel to create their Dr. Robert pedal.
If you love the unique guitar sounds from the Beatles Sgt. Pepper/Magical Mystery Tour and even the White Album period as well as The Rolling Stones Between The Buttons, Satanic Majesties and other 66-68 recordings and Jimmy Page’s sound on the first two Led Zepplin records... this is for you.
It isn’t a one trick pony or a gimmick by any means though. It is very responsive to individual playing and can be tweaked endlessly to create new sounds.
I’ve used it in a few recordings to get a chunky rhythm guitar sound as well as lead tones that easily cut through a mix.
By watching some YouTube video demonstrations and using the excellent User Guide, you can dial in sounds that you won’t find with other devices.
I suggest having a listen to the guitars on the albums I noted and you’ll see why this pedal isn’t like anything you may have.
It will be well worth getting and it’ll be hard to stop playing through it.

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.

Dr Robert

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!

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
