Zoom A1 FOUR Acoustic Multi-Effects Pedal

The Zoom A1 FOUR is a high-versatility multi-effects pedal designed specifically for acoustic instruments — not just guitar, but also saxophone, trumpet, violin, harmonica, and acoustic bass. It’s built to give you rich tone, creative flexibility, and reliable live performance tools in a compact stompbox.

Key Features:

• 80+ Effects — Includes over 80 onboard effects, with more than 35 completely new ones designed especially for acoustic instruments. 
• Acoustic Modeling — Offers acoustic guitar modeling (AG Models) using impulse response (IR) technology to emulate the body resonance of different guitar shapes. Each model has adjustable parameters (Gain, Bass, Mid, Treble) to shape your tone.
• Pickup Selector — Lets you set processing based on your instrument’s pickup type (piezo or magnetic) and apply a dedicated EQ modeled on a variety of analog processors.
• Looper & Rhythm Machine — Built-in looper records up to 30 seconds (64 beats), and there are 68 rhythm patterns tailored to acoustic styles (jazz, reggae, samba, and more) to jam with or build layered arrangements.
• Anti-Feedback Filter — Automatically detects and cuts out frequencies that cause feedback — very handy for live acoustic setups.
• Two Performance Modes —
• Memory Mode: Program a setlist of patches and switch between them seamlessly.
• Stomp Mode: Enable or bypass individual effects with your foot, offering flexible real-time control.
• Tuner — Integrated chromatic tuner supports standard, open, and drop tunings. 
• Powered by Battery or USB — Runs on 4 × AA batteries (up to ~18 hours) or via USB (for power, MIDI, and firmware updates through Zoom’s Guitar Lab software).
• Software Integration — Compatible with Zoom Guitar Lab, letting you edit patches, build custom sounds, and explore additional factory or user-created presets.
• Mic Amp Included — Comes with a Zoom MAA-1 mic amp to connect a microphone (dynamic or condenser) easily and apply all the same effects. 

Why You’ll Love It:

• Tailored for Acoustic Players — Designed specifically with acoustic instruments in mind, so the effects feel natural and musical rather than overly “electric.”
• Great for Live Performance — The anti-feedback filter, onboard rhythm, and looper make it ideal for gigging soloists or singer-songwriters.
• Creative Flexibility — From warm acoustic amplifier simulations to ambient reverb, modulation, and even sax or trumpet-specific effects, you can explore a wide tonal palette.
• Portable & Reliable — Compact enough for pedalboards, yet powerful enough to use in rehearsal, studio, or on stage.

If you want a dedicated effects processor for acoustic instruments — one that handles tone modeling, looping, and creative effects all in one box — the Zoom A1 FOUR is a superb, all-in-one tool.
