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...
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...
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...

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...
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...
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

Dr Robert Rocks
This is an amazing Pedal. Authentic & Versatile. Blown away.
The Dr. Robert is no one-trick pony. Its overdrive, fuzz, and boost
"The tones within are so close to the Beatles tones I’ve been chasing for decades, and so unique in non-Beatles contexts."
The Dr. Robert is a bit of an art piece as well
“The cool-sounding is a worthy and interesting addition to anyone’s stompbox collection.”
"Here's your prescription to replicate The Beatles’ Vox UL 730 amp sounds"
"An obscure and largely forgotten amp gets rightly put back on the map in a versatile drive pedal with visceral power and a raw grind that will find a role in many kinds of music."
Sonically, the Dr. Robert is a joyous experience.
“Pushing up the gain yields a surprising amount of grind and sustain. Kicking in the “Mach Schau” boost takes things into another level entirely.”
This pedal is just what the doctor ordered.
“Custom FET circuitry provides the sag and sound of tubes, while the middle control increases the sweet saturation effect.”
Not just for Beatles fans, but definitely for Beatles fans.
“The llustration by “Revolver” cover artist Klaus Voorman really brings that spirit and feel of those classic LPs back to life, and the sounds fit perfectly as well”
