Boss AD-3 Acoustic effects pedal

A compact, dedicated floor processor made by Boss specifically for acoustic-electric guitars (discontinued). It was designed to fix the two biggest live problems with piezo pickups: thin/dry tone and feedback. Key features: • Bottom and Top tone controls — specialized filters (not regular EQ) that add body/warmth and sparkle more naturally than a standard tone stack. • 2×2 Chorus — split-frequency (low + high) processing for a smoother, more natural chorus that doesn’t get muddy. • Acoustic-tuned reverb. • Dual anti-feedback system (manual frequency + Auto mode via the left footswitch). • Stereo balanced line outputs for direct-to-PA, plus a special Guitar Amp output mode. • Input level control, peak LED, battery or Boss PSA 9V power. It’s a practical one-box solution for gigging acoustic players who want better tone and feedback control without a full preamp/DI rack.
