About Dr Scientist

Dr. Scientist pedals are designed and built by husband and wife team Ryan and Tanya Clarke, who live with their dog Little Miss in Sherwood Park, Canada, a small town outside Edmonton. Ryan, a graduate of the Northern Alberta Institute of Technology's Electronics Engineering Technology program, designs the circuitry while Tanya, a graduate of NAIT's graphic sign arts program, designs the finishes.

There's no contract workers, interns, piece workers or day labourers: we build each and every pedal.

Our pedals offer a higher level of control than can be found on any other pedal available in the known universe, while being intuitive and easy to use. They're designed to work with all types of instruments, give you power over every single audible parameter, mix wet and dry signals and use CV. All but the Reverberator are fully analog, all the stereo pedals are true stereo—two signals in, two signals out. Dr. Scientist pedals let you create sounds that are unique to you.

They're designed with the working musician in mind: top-mounted jacks save room on the pedal board, soft touch switches last a million on/off cycles without needing repair, out-of-this-world finishes mean that gear heads will envy you wherever you play. All that and we stand behind what we do: we offer a lifetime, fully-transferable, nearly-unlimited warranty.

Dr. Scientist pedals are available at 44 dealers around the world. We're one of the few pedal companies where if you send an email you'll reach the guy who designs, builds and ships the product to you. So go ahead, get in touch. We really appreciate all of our customers and we'd love to hear from you.

The Heisenberg Molecular Overdrive

By the 24th century, nanobots have solved all of humanity’s problems, from the common cold to socks with sandals. With billions of nanobots out of work, Dr. Scientist—with help from the National Research Council of Canada, the National Institute for Nanotechnology and the University of Alberta—developed a way to use nanotechnology to create a molecular junction, a new kind of diode that saturates in a slower, smoother, more pleasing way than conventional, silicon diodes. What resulted was a new kind of overdrive pedal, featuring three gain stages: a MOSFET booster, an NPN transistor fuzz and an opamp distortion.

The Elements

Your guitar tone is like the elements of space after the big bang, floating through a vacuum in disharmony, their potential infinite but unrealized. Realize their potential and bring your tone into harmony with the Elements, a pedal that delivers overdrive, distortion and equalizer, and works with guitars, basses and electronic instruments. The Elements provides so much control over your tone, you'll think you're sitting at the control deck of a flying saucer, but its intuitive design means you won't need to check the manual every five minutes. Oriented toward high-gain tweakability, the Elements gives you the control you need while blasting a mean tone.

If you’re on a quest that takes you far from home, you can’t be weighed down. You never know when you’ll need to duck under a laser cannon, or fight a giant eyeball, and you need to have portable and practical tools to face whatever alternate reality lays in store. It’s the same thing with your tone--sometimes it pays to have a compact, digital multi-tool that covers a wide range of tone needs. Enter the BitQuest: Complete with eight digital effects that work with or without a built in digital fuzz, the BitQuest offers flanger, HP/LP filter, bit crusher, infinite reverb, notch filter, ring mod, pitch shift and glitch delay, all in one pedal. No matter where the future takes you, BitQuest has got you covered.

Spectrum Analyzer

In 2219, Dr. Scientist’s sister, Professor Scientist, patented a method for turning information into food, revolutionizing humanoid societies: without the need for nourishment, information became the world’s most important commodity. It was traded in markets, in bazaars and on the Futurenet. Dr. Scientist took advantage by developing the Spectrum Analyzer, a device which reads audio information and displays it in seven frequency bands, from 63Hz to 16kHz, represented by LEDs. It reads information from any source that can be plugged into it—a computer, a guitar, a synth, a cellphone—or it can read the sound around it through a built-in microphone. Musicians hungry for information can see their music in realtime, represented by light.

The gravity wells of the Alpha-9 quadrant are the universe's deepest, their ability to expand matter legendary throughout the stars as powerful and unyielding. It is from these gravity wells that Dr. Scientist's Reverberator pedal takes its influence: with nine different reverb effects you can go from the deepest, wettest recesses of space to a tone-enhancing small room. Use the mix knob to blend your wet, reverberating signal with your analog dry signal, control the gain and rate of decay, have control over all aspects of your tone. Don't be caught cruising the cosmos without this kind of power.

The Tremolessence

In 2397, technology to traverse dimensions through black holes is widespread. It involves using sound waves to disintegrate matter at the atomic level, only to reintegrate it later. Whether you're going for a subtle texturing or you want to whub-whub until your spaceship's very materiality begins to disintegrate, the Tremolessence is where to start. A true-stereo analog tremolo pedal, the Tremolessence offers a wide range of options to oscillate the hell out of your sound. It lets you fine tune the rate of the tremolo, the depth, the shape of the waveform and even lets you pan the sound so that you can make your tone your own. When you need to blow minds, the Tremolessence is the pedal for the job.

Frazz Dazzler

In the outer recesses of space lays Zeta-6 quadrant's largest junkyard. Here, gravity-challenged junkers float about rubbing their rusted hulls together, while the sounds of these frictions reverberate into the worlds around them. Want your tone to sound like two abandoned spaceships crashing in the vacuum of space, their oxidized wings gnashing together and disintegrating into dust? With a wide gain range, the Frazz Dazzler pedal will frazzle dazzle you with its mean-spirited and aggressive fuzz whether you play guitar, bass or an electronic instrument.
