Boss AD3 Acoustic Instrument Processor

A World of Acoustic Expression Awaits

AD-3 Acoustic Instrument Processor •

The AD-3 Acoustic Instrument Processor incorporates the groundbreaking

acoustic processing technology of BOSS' popular AD-5

unit in a smaller, gig-friendly compact pedal design. Developed

exclusively for live performance, the AD-3 gives guitarists a

warmer, richer acoustic sound thanks to its tone shaping controls

specially tailored for acoustic-electric guitars, high-quality reverb

and chorus, as well as a built-in feedback eliminator. Quite simply,

this compact pedal is an acoustic musician's best friend.

• Footswitchable Bi-Stereo Chorus offers split-frequency

processing (Low and High) for natural, smooth chorus

effect

• Studio-quality reverb provides clear, deep reverberation

specially tuned for acoustic guitar

• Newly developed Bottom and Top controls offer

variable tonal shaping to eliminate dry sound from

piezo pickups and add rich, resonant lows and brilliant

highs as desired

• Special Guitar Amp output provides proper impedance

and tonal balance for great-sounding connection to a

guitar amp; stereo balanced outputs allow for direct

connection to PA

• Dual Anti-Feedback function can be manually set to

eliminate feedback or can be set to Auto mode via

footpedal

• Battery or AC-powered for maximum flexibility

Adding Rich Expression to Your Acoustic-

Electric Guitar

The AD-3 Acoustic Instrument Processor pedal solves the

age-old acoustic-electric guitar dilemma (i.e., thin tone and

feedback problems) by giving guitarists specially developed

tone, reverb, chorus and Anti-Feedback control in a highquality

compact pedal. Its built-in footswitchable 2x2

Chorus provides a smooth effect which can be precisely tailored

using an onboard depth control, adding just the right

amount of stereo sparkle. The reverb is exceptionally deep—

perfect for simulating a mic'd acoustic guitar—and can also

be adjusted via a depth knob.

But where the AD-3 really shines is in its onboard tone controls,

aptly named Bottom and Top. Far more effective

than simple EQ knobs, these controls incorporate sophisticated

filters which work differently when boosted and cut.

The Top knob boosts high-end brilliance or can be used to

eliminate the thin, dry sound characteristic of most piezo

and magnetic pickups, making your tone more natural. The

Bottom knob tunes the low frequencies to add the desired

amount of rich body resonance. Combined with the AD-3's

built-in Anti-Feedback controls—which can be manually set

or set via footswitch to Auto—this pedal offers the perfect

tone-enhancing, feedback-eliminating solution.

Flexible Connections

The AD-3 offers an adjustable Input control for impedancematching

to a variety of acoustic-electric pickup types.

Similarly, its Output section provides a choice between

stereo balanced outputs for direct connection to a PA system,

or a dedicated Guitar Amp output for plugging in to a

guitar amplifier.
