A BOSS Preamp Designed for the Modern Electro-Acoustic Guitar
With the AD-2, BOSS offers a compact preamp aimed at electro-acoustic guitarists who want to regain a more "woody" and organic feel when plugging in their instrument. The idea is clear: to provide a natural, studio-level sound in a pedal format, with discreet yet sophisticated processing controlled by a few simple knobs. Whether on a pedalboard or in a minimal setup, the AD-2 acts as a reliable sonic foundation to transform a sometimes dry piezo signal into a more lively tone, ready to be sent to an acoustic amplifier or directly to the front of house.
Who and In What Contexts Does the AD-2 Make a Difference?
The BOSS AD-2 is aimed at acoustic guitarists playing live concerts, rehearsals, or studio sessions who want to save time on settings while improving the perceived quality of their amplified sound. It suits both beginner stage musicians (who need a simple and reassuring solution) and experienced guitarists looking for an efficient tool to smoothly run soundchecks without stress.
In terms of styles, it is particularly relevant for pop, folk, variety, country, chanson, and pick-style accompaniment or fingerpicking-anywhere a defined, warm, and stable acoustic presence in the mix is expected. Thanks to its balanced DI output, it naturally integrates into a "guitar to PA" setup while keeping a dedicated output for an acoustic amp on stage.

Questions frequently asked
Does the BOSS AD-2 improve the sound of a piezo pickup?
The Acoustic Resonance processing recreates depth and resonance to reduce the dryness sometimes associated with piezo pickups. The output emphasizes more body in the low-midrange and a softer attack.
How to connect this pedal to a PA system and an acoustic amplifier?
The balanced LINE OUT 6.35 mm TRS jack allows sending the signal to a mixing desk. The OUTPUT 6.35 mm jack can feed an acoustic amplifier, with a recommended load impedance of 10 kOhms or higher.
Does the AD-2's notch filter help against feedback?
The NOTCH control targets a problematic frequency to reduce feedback, especially in challenging rooms.
Can the guitar be tuned silently with this pedal?
The Mute function, accessible via footswitch, cuts the signal for tuning or instrument changes without unwanted noise. The bypass is buffered, which helps preserve signal clarity over long cables.
What power supply is required for this acoustic preamp?
A BOSS PSA series power supply, sold separately, can be connected to the DC IN input. Current consumption is 55 mA. An alkaline battery provides about 6 hours of operation.
