The Zoom A3

The perfect acoustic accompaniment

Reproducing the delicate tone of an acoustic guitar onstage can be challenging. Pickups have a tendency to make the sound flat and lifeless, while microphones often introduce feedback. Zoom's A3 provides the perfect solution. This compact pre-amp/effects pedal provides everything you need to restore and enhance the natural tone of your instrument, or even transform it into a different-sounding one altogether. Powerful remodeling features combined with great-sounding effects and advanced features such as feedback suppression, auto-chromatic tuner, 3-band equalization and a Clean Boost foot switch make the A3 the complete sonic toolbox for acoustic guitar.

Dozens of ways to restore and reshape the sound of your guitar (Headline)

The A3 provides remodeling presets for 16 different body types/shapes and 28 world-renowned acoustic guitars, allowing you not only to restore the true sound of your guitar but to simulate the tonal characteristics of other instruments as well. In addition, there are 40 onboard DSP effects, each carefully crafted to enrich the tone of acoustic guitar. For ease of use, these are organized into the following categories:

Body and model types – You'll find many popular acoustic guitar bodies and types here, from Dreadnought to Jumbo, from Round Shoulder to Square Shoulder, and from Single Cutaway to Resonator. Also included are emulations of Martin 00 and 000 models, resin-body guitars such as the Ovation Adamas, and both twelve-string and nylon-strings—even upright bass. All A3 models accurately recreate the tonal differences between instruments, down to the bracing and type of wood from which they are made.

Dynamics Effects / Filters – Shape and tame your sound with 10 compressors, equalizers, exciters and wah effects, along with Zoom's Noise Reduction (ZNR) algorithm, designed to remove noise during pauses while still maintaining your instrument's natural tone.

Modulation – Add the shimmering silkiness of phasing, flanging, chorus, tremolo, vibrato, detuning and pitch shifting with these 9 effects.

Delay – The A3 provides 5 different kinds of delays, including reverse, multi-tap and self-oscillating delays.

Reverb – A dozen adjustable rooms, halls, arenas, plates and springs that allow you to add depth and spaciousness to your sound. The A3's cutting-edge DSP microchip performs 32-bit floating-point calculations, giving it the ability to create sophisticated studio-quality effects such as the realistic simulations found here.

Mic – Three different microphone models: emulations of the popular Shure SM57, AKG C414 and Neumann U87.

Full-featured and easy to use

The A3 offers a super-low noise floor and provides separate input jacks for both pickup and microphone, with dedicated gain controls for each, as well as a master level knob and a wet/dry balance control. A three-way Pickup Select switch allows the A3 to be used with piezoelectric, magnetic and passive pickups, and the phase of the mic input can be reversed. You can even apply phantom power (+24 or +48 volts), enabling the use of condenser microphones.

There are dual line-level output jacks for connection to a PA; headphones can also be connected here for private monitoring. In addition, a balanced XLR output with a Ground switch enables the A3 to be used as a direct box.

The A3's intuitive graphic interface allows easy navigation and makes creating and editing effects a breeze. You can use up to 3 effects simultaneously and arrange them in any order you like. There are 20 patch memories where you can store your custom edited and chained multi-effects. An Auto Save function ensures that edits you make are automatically saved, and you can create a list of up to 26 patches to cycle through as you step on the foot switch—handy for live gigs or whenever you want your effects in a certain order.

The onboard chromatic tuner supports a variety of standard guitar tunings, including drop tunings, and you can opt to either bypass all effects during tuning or to mute the outputs so that you can tune in silence. Lastly, a Tap Tempo feature enables you to to set delay times and modulation effect frequencies in real time to the rhythm of the song you're playing.

Advanced features

The A3 is packed with advanced features for the acoustic guitarist. Three-band equalization allows you to shape your sound to compensate for the acoustics of every environment, and an Anti-Feedback circuit automatically detects ringing and eliminates up to three frequencies simultaneously, with minimal effect on tonal quality. A Clean Boost control with adjustable tone enables you to add up to 12dB of extra gain at the touch of a foot switch—useful for those moments when you need to step into the spotlight and feature your instrument—and there's a low cut filter for the removal of rumble and other low frequency noise. Last but not least, there's a USB port for connection to your computer for firmware updates.

The A3 runs on just 4 AA batteries—either alkaline or rechargeable NiMH—or you can use the supplied AC adapter. Battery life is up to 8 hours with alkaline batteries, allowing you to use the A3 with confidence from rehearsal to the main stage. An "eco" function automatically turns the pedal off if unused for extended periods.
