The Mooer Audiofile is a Hi-Fi quality analog headphone amplifier in a convenient micro pedal configuration. The Audiofile's class A amplifier circuit will bring a smile to the faces of even the most discerning musician. The Audiofile can be placed at the end of your pedalboard for easy switching between amplified or silent practice. With headphones connected, activate the analog cab sim for immersive practice sessions which won't disturb your neighbours. When performing live the Audiofile can be completely bypassed thanks to its true-bypass switching. Alternatively, the Audiofile can be used as an always-on‚¬ï¿½ signal buffer/booster, just remember to disengage the cab simulation. Clarity, warmth, dynamics and uncoloured tone are what the Audiofile brings to your pedalboard. Main Features *Professional headphone amplifier designed for use with guitar and bass pedalboards.
