In addition to the choice of wood and construction, electric pickups are decisive for the basic sound of the instrument. Many an inexpensive model can be significantly upgraded by retrofitting it with brand-name pickups. The character of a brand instrument is also significantly changed by replacing the pickups. Last but not least, pickups are an important spare part, indispensable for repairing defective electrics.Besides the big instrument makers Fender and Gibson, several manufacturers have specialised in the development of pickups over the years. Brands like Seymour Duncan, DiMarzio and EMG played a pioneering role in the development of alternative sound characteristics. Currently, innovators are making a name for themselves in the industry, with Amber, Suhr, Bare Knuckle, Staufer, Fishman and others in the JustMusic range.
