Dunlop Manufacturing

Scottish immigrant Jim Dunlop founded the Jim Dunlop Company in 1965 as a part-time business while working as a processing and chemical engineer at Barr and Stroud in Glasgow. He was an apprentice of the creator of the first hip replacement, William "Bill" Wallace. His first product was the Vibra-Tuner, a small device that attached to a guitar with a suction cup and displayed whether the guitar was in tune with the vibration of a small reed.

While visiting music stores to sell his new product, someone told him that musicians needed a good capo, remarking that anyone who made a good capo that could handle a 12-string guitar would make a lot of money. Using his engineering background, Dunlop created the toggle capo, and then worked with a local machine shop to build the first capo dies, manufacturing what eventually became the long running "1100 series" capo.

Starting from his living room, Dunlop later moved construction to his garage, and then to a location outside the house.

On March 19, 1972, he moved into the pick market, after reading every issue of Guitar Player magazine and noting musicians’ comments concerning what they liked and did not like about picks. He made his first picks from nylon, and although Jim Dunlop, Sr. is no longer alive, the Dunlop Manufacturing company continues to produce these, among many other types.

Also in 1972, Dunlop left his job at Dymo Industries to focus on his own company full-time. He moved his family to Benicia, California and set up shop in Benicia Industrial Park. A few years later, he outgrew that building and moved to Industrial Way.

Dunlop products now range from capos and picks to slides, strings, fret wire, strap retainers, and a variety of electronic effects, including the original Cry Baby wah-wah pedal, the Uni-Vibe phaser, Heil Talk Box, and the MXR and Way Huge lines of stompboxes.

Dunlop Manufacturing founder Jim Dunlop Sr died on February 6, 2019, at the age of 82.
