With specially engineered effects, built-in looper and drum machine, the Zoom A1 FOUR is the first Multi-Effects Processor designed for a variety of acoustic string and wind instruments, including bowed strings!

The A1FOUR is preloaded with over 80 effects, including more than 35 new groundbreaking effects designed and engineered for acoustic instruments. The A1 FOUR comes with 8 additional pedal-controlled effects to adjust volume, pitch, reverb, delay, and wah.

Turn your violin into an orchestra with the 'Vn Orchest' preset patch! From the rich, full sound of a string symphony to the raw, distorted explosion of metal, the A1 FOUR has effects for every genre.

Don't have an electric violin, or don't use a pickup? No problem: just mic yourself! The included Zoom MAA-1 mic adapter provides a hassle-free microphone connection to the A1 FOUR. It works with dynamic microphones and even provides phantom power for condenser mics. Add effects to any acoustic instrument and adjust gain settings with the MAA-1’s easy-access controls.
