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.

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.
