BOSS’s COSM Acoustic-Modeling technology is beautifully showcased in this small but powerful pedal, which simulates an acoustic guitar much more precisely and realistically than previous technology allowed. Derived from BOSS top-of-the-line AD-8, the AC-3 simulates the sound of an acoustic guitar with incredible precision. Four simulation modes are provided: Standard, Jumbo, Enhanced, and Piezo-equipped; the latter supplies that famous “cut through the mix” direct piezo sound. Previous compact acoustic-guitar modeling-pedals were promising, but now the bar has been raised with AC-3.
