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

"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”
