Guitar Pedal: The heart of the AD-10 is BOSSs groundbreaking Acoustic Resonance processing. With this technology, the AD-10 allows the complex body and string resonances that so many other pickup systems lose. The result is, you get an expressive, organic vibe that is the heart of acoustic playing. There are also transparent anti-feedback controls, memory locations for sound setups, an 80-second looper, USB audio, and more. The Acoustic Resonance processing designed by BOSS also analyzes the saddle-based piezo pickup signal and re-creates the missing body and string resonances so that your tone is full and expressive of the entire instrument. Subtle strums, finessed leads, or full-on attacks all find a home through the AD-10 and allow you to show your range.
