The ZOOM 504 II Acoustic is a versatile multi-effects processor engineered for acoustic and electric guitarists. Featuring De-AMP technology to eliminate harshness when running acoustics through amplifiers, plus AIR and TOUCH effects for spacious, refined tone. The built-in acoustic simulator transforms electric guitar sound, making live switching between instruments seamless.
Equipped with an automatic feedback suppressor that detects and eliminates howling frequencies via footswitch control, plus an integrated chromatic tuner for quick on-stage tuning. The dual power supply runs on either AC adaptor or four AA batteries—up to 28 hours with alkaline cells.
Compact and more refined than its predecessor, the 504 II includes the world's first wah effect designed specifically for acoustic guitar, plus the EMPHASIZER for authentic resonator tones. Compatible with optional footswitch (FS01) and expression pedals (FP01/FP02) for real-time control. Ideal as a live processor or recording preamplifier for both acoustic and electric instruments.
