Founded in 1981 by engineer and musician Larry Fishman in Andover, Massachusetts, Fishman is a leading manufacturer of acoustic and electric guitar pickups, amplifiers, and related electronics. The company began when Larry Fishman built a prototype acoustic bass pickup in his basement to solve his own amplification challenges, and an early OEM deal with Guild Guitar Company in 1983 — followed by Martin Guitar — launched the brand into wider recognition. With over forty patents to its name, Fishman has become synonymous with acoustic amplification, and its Matrix undersaddle pickup and Aura Acoustic Imaging technology are widely regarded as industry standards.

Fishman's Loudbox amplifier series — spanning the Micro, Mini, Mini Charge, Artist, and Performer models — is the best-selling acoustic amplifier line in the world. Beyond acoustics, the company's Fluence pickups represent a fundamental departure from traditional wire-wound coil designs, using multi-layer circuit boards derived from aerospace and telecommunications technology to deliver hum-free, multi-voice electric guitar and bass pickups. Other notable product lines include Rare Earth soundhole pickups, PowerTap energy-harvesting systems, the TriplePlay wireless MIDI guitar controller, the Powerbridge piezo bridge system, and the AirLock wireless instrument system.

Fishman pickups are installed as OEM equipment in guitars from manufacturers including Fender, Martin, PRS, Gibson, Ibanez, ESP, Schecter, and Cort. The company's Fluence artist roster includes signature pickup sets for Tosin Abasi (Animals as Leaders), Devin Townsend, Mick Thomson (Slipknot), Tim Henson and Scott LePage (Polyphia), Will Adler (Lamb of God), Stephen Carpenter (Deftones), and Greg Koch, among others.

Fishman has 109 products cataloged on Equipboard, including Electric Guitar Pickups, Acoustic Guitar Pickups, and Combo Guitar Amplifiers. Their gear is featured by 192 artists, with the strongest followings in Rock, Metal, and Folk, World, & Country. Notable users include Ryan "Fluff" Bruce, Hunter Agufish, and Greg Koch. Fishman's catalog spans the full price spectrum — from entry-level options to high-end flagships.
