New COSM Acoustic Modeling
----------------------------------------------------------------------------------------------------------------------------
Nothing beats the sound of a fine, miked acoustic, but budgets and feedback issues often force musicians to use a more affordable electric-acoustic instrument with often thin-sounding piezo pickups. Thanks to the AD-8’s innovative COSM Acoustic Modeling technology, you can transform your ordinary acoustic guitar into one of six high-end guitars like Martin and Gibson—a world’s first! The AD-8 even simulates the popular “miked acoustic” sound via its Body and String Enhance controls.

Flexible Tone Editing

The AD-8’s high-quality reverb effect was designed specifically for acoustic guitar. The reverb can be adjusted to create anything from a slight touch of ambience all the way to rooms and halls—perfect for adding spaciousness to your sound. And with onboard 4-band EQ, you can shape your tone to suit any style of music or venue.

Designed with the stage musician in mind, the AD-8 offers several convenient features for performance, starting with an onboard tuner based on BOSS’ acclaimed TU-Series.

In addition to unbalanced stereo outputs and a dedicated Electric Guitar Amp output, the AD-8 comes with a pair of XLR outputs. These balanced stereo outputs are true DI-complete and include a ground lift feature for eliminating hum. They’re the perfect way to connect to a PA system or to professional recording gear. With the BOSS AD-8, you’ll sound great whether on stage, at home or in the studio.
