The AC-3 gives electric guitarists an acoustic effect with a tap of the pedal...
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 has allowed. Derived from BOSS top-of-the-line AD-8, the AC-3 pedal 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 Boss AC-3.
