    Product Description

    The Boss AD8 Acoustic Guitar Effects Processor lets you take that dry, pinched piezo output from your favorite live acoustic and turn it into a truly incredible-sounding warm instrument. The AD8 uses COSM modeling technology to transform the piezo pickup sound of an ordinary electric/acoustic into your choice of six high-end acoustic guitars. Models include Martin D28/00028, Gibson J45, Guild D40 and Jose Ramirez. The versatile Boss AD8 can also simulate the warm sound created by miking the guitar's neck and body - a world's first. It accomplishes this by modeling several of the greatest classic mics anywhere, including the Neumann U67 and 87 and the AKG C12. Controls include Body and String Enhance to simulate warm, miked acoustic sounds. The Boss AD8 provides high-quality reverb, tailored for acoustic guitar, 4-band EQ, Anti-Feedback control and an onboard TU-2 type chromatic tuner with Mute function. Four Preset memory locations instantly switch acoustic models. With balanced DI-style XLR outputs for direct connection to PA systems (and 1/4 inch as well) and sturdy floor-based metal pedals make the Boss AD8 perfect for studio or stage.

    The BOSS AD-8 Acoustic Guitar Processor uses COSM modeling technology to transform the piezo pickup sound of an ordinary acoustic into six of the world’s most sought-after acoustic guitars.

Other handy features include a pro-quality reverb tailored for acoustic guitar, 4-band EQ, a convenient Tuner function and preset memories.

    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. *All trademarks are property of their respective owners.

    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.

    A Live Performer’s Dream
    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. Just click the pedal to mute the guitar sound and tune up while referencing the LED display. Onboard memory lets you store your favorite settings and switch between them instantly, while Auto Anti-Feedback eliminates embarrassing feedback.

    Professional Connections
    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.
