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 to the gig isn’t 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.


  • BOSS’s most advanced acoustic-guitar modeling in a compact pedal
  • Four simulation modes: Standard, Jumbo, Enhanced, and Piezo-equipped
  • Top and Body knobs for fine-tuning the virtual-body resonance
  • Built-in reverb, optimized for acoustic-guitar simulation
