Designed to elevate your acoustic instruments to new heights, the A1 Four from Zoom is the first multi-effects processor designed specifically for acoustic string and wind instruments, packed with 80 high-quality effects, including 35 effects dedicated to acoustic instruments, and a sophisticated acoustic guitar emulation engine that uses specially recorded IRs for a true-to-life transformation of your guitar tones. You can run and chain up to five simultaneous 32-bit effects in any order you want in up to 50 user-defined patches, and with 68 rhythm patterns, a chromatic tuner, and a comprehensive internal looper that can store up to 30-second loops, you have a powerful toolset for unlocking the full scope of your creativity.

A 1/4' output combines line amp and headphone output into one, so you can easily connect to a PA system, your guitar amp, or high-powered headphones with support for 17mW per channel into a 32-ohm load. The extra USB Micro-B connection lets you power your pedal, provides MIDI I/O, and can be used to connect to the free Guitar Lab software for creating and editing effects or patches, and the A1 Four can also run on four AA alkaline batteries on-the-go, providing up 18 hours of battery life. The A1 Four includes the MAA-1 Mic Amp, which makes it easy to connect dynamic and phantom-powered condenser microphones to your processor.
