Boss AC-3 Acoustic Simulator BOSS is pleased to offer another "Authentic BOSS" Compact Pedal; the AC-3. How many times have you been onstage or in the studio with your electric guitar, and wished that you'd brought an acoustic along? For musicians who travel light, hauling an extra guitar isn't practical. 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.
