A3 Preamp

The Zoom A3 acoustic preamp and multi-effects processor offers modeling and effects for acoustic instruments, featuring 16 acoustic body models and 28 guitar emulations to replicate or transform instrument tone. This acoustic preamp pedal includes 40 onboard DSP effects, organized by type such as dynamic processing, modulation, delay, and reverb. The A3 models various acoustic body shapes—including dreadnought, jumbo, 12-string, nylon, and even upright bass—along with different tonewoods and construction details. Dynamics options cover compression, EQ, exciter, wah, and Zoom Noise Reduction (ZNR), while the modulation section offers chorus, flanger, phaser, tremolo, vibrato, and pitch shifting. Five selectable delay types and twelve reverb simulations provide further tonal shaping. The unit also includes microphone modeling for three classic condenser and dynamic mics. **Features:** - 16 acoustic body type emulations and 28 classic acoustic guitar models - 40 built-in DSP effects, including compressor, EQ, exciter, wah, and noise reduction - Modulation effects: chorus, flanger, phaser, tremolo, vibrato, detune, pitch shift - Multiple delay types (reverse, multi-tap, oscillating) and twelve reverb simulations (room, hall, plate, spring, arena) - Microphone preamp modeling with emulations of Shure SM57, AKG C414, and Neumann U87 - 32-bit floating-point DSP for high-quality, studio-grade processing
