Fishman acoustic amplifiers are designed for accuracy and transparent sound of acoustic instruments, including acoustic guitar, acoustic bass, mandolin, violin, cello, banjo, and more. Fishman amplifiers can also be used with solid body instruments like electric guitar and bass. For these instruments, acoustic voicing can deliver increased high frequencies when compared to a traditional electric guitar amplifier but the tone is more open and life-like. Fishman doesn’t recommend using distortions or overdrives with our acoustic amplifiers. The speakers are designed for fidelity and are not built to tolerate the square waves that distortions and overdrives produce.
