The Zoom A1 Four is jam-packed with more than 80 effects — 35 of which are tailor-made for specific acoustic instruments, including acoustic guitar, saxophone, trumpet, violin, harmonica, and acoustic bass. With the A1 Four, you can turbocharge your performances with distortion, chorus, wah, and more. Building patches is a breeze, thanks to Zoom’s Guitar Lab software. Playing live with the A1 Four is just as effortless, with two performance modes, hassle-free microphone connection (including phantom power for your condenser mics), and an anti-feedback filter. You also get a built-in drum machine with 68 rhythm patterns and a 30-second looper!
