The Story
DESCRIPTIONÂ
BOSS is pleased to offer another âAuthentic BOSSâ Compact Pedal; the AC-3. How many times have you been onstage or in the studio with your electric guitar, and wished that youâd brought an acoustic along? For musicians who travel light, hauling an extra guitar to the gig isnât always the most attractive option. BOSS AC-3 to the rescue! This new-generation compact pedal employs COSM modeling technology to transform any electric guitar into a variety of beautiful acoustic guitars.
Advanced Modeling
BOSSâs 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 âcut through the mixâ direct piezo sound. Previous compact acoustic-guitar modeling-pedals were promising, but now the bar has been raised with AC-3.
Fine Control
Top and Body controls are provided for shaping the characteristics of the four acoustic models. Create the perfect acoustic-guitar sound quickly and easily with simple knob twists.
Reverb Included
Add depth and sweetness to the sound with the AC-3âs built in digital reverb. Itâs like getting two pedals in one!
Versatile Output Paths
Two sets of outputs are provided for connecting the AC-3 to a standard guitar amp and to a direct input device such as a PA, recorder.
