Forget lugging multiple guitars to your next gig – the BOSS AC-3 Acoustic Simulator brings authentic acoustic tones to any electric guitar through advanced COSM modelling technology. This compact pedal addresses the common dilemma faced by travelling musicians who need acoustic sounds but can’t justify carrying extra instruments to every performance or recording session.
Building on the foundation of BOSS’s flagship AD-8, the AC-3 offers four distinct simulation modes: Standard, Jumbo, Enhanced, and Piezo-equipped. The latter provides that characteristic direct piezo sound known for cutting through dense mixes. With dedicated Top and Body controls, musicians can quickly shape the acoustic characteristics to suit their musical requirements, while the built-in digital reverb adds natural depth and warmth to the sound.
The AC-3’s practical design includes dual output options, allowing simultaneous connection to both guitar amplifiers and direct input devices such as PA systems or recording equipment. This versatility makes it an essential tool for performers and studio musicians who demand professional acoustic guitar sounds without the complexity of additional instruments.
