Dr. Scientist is a boutique guitar effects pedal company founded in 2005 and based in the Okanagan Valley of British Columbia, Canada. The company was started by Ryan Clarke and Tanya Clarke and has since grown to include Neil Graham, with the small team handling design, programming, assembly, and graphics in-house. Pedals are hand-built in Canada in relatively small batches.

The brand is known for unconventional, multi-mode stompboxes that often blur the line between traditional pedal categories. Notable products include the BitQuest, a multi-effects unit packing eight digital effects with an analog fuzz, and a Eurorack version of that circuit; the Frazz Dazzler, a dual-channel fuzz with a flexible EQ; The Elements, a combined wide-range equalizer, overdrive, and high-gain distortion; the Sunny Day Delay; the Dusk resonant low-pass filter; the Phreak ring modulator; the Spectrum Analyzer; and the compact BoostBot clean boost.

Dr. Scientist pedals tend to appeal to players looking for versatile, exploratory tones rather than straightforward vintage-voiced effects, and the brand has built a following in the boutique pedal community through dealers such as Reverb, Chicago Music Exchange, and other independent retailers worldwide.

Dr. Scientist has 6 products cataloged on Equipboard, including Reverb Effects Pedals, Overdrive Effects Pedals, and Delay Effects Pedals. Their gear is featured by 1 artist, with the strongest followings in Rock. Notable users include Mike Moya.
