Description

The Boss AD-2 Acoustic Preamp is your gateway to achieving pristine, natural acoustic tone on any stage or in the studio. This compact pedal is designed for acoustic-electric guitars, providing a remarkable blend of advanced processing and user-friendly controls. With Acoustic Resonance, the AD-2 analyzes your guitar's input signal, recreating the complex resonance of an unplugged acoustic. This feature transforms the often-quacky sound of piezo pickups into a warm, full-bodied tone. The pedal's Ambience control adds professional-quality reverb, enriching your sound with depth and dimension without overpowering the natural character of your instrument.

This pedal also includes essential tools for live performers. The Notch filter is a simple yet effective way to combat unwanted feedback, and with its dual-output design, you can seamlessly switch between an acoustic amplifier and a direct PA connection. For added convenience, the AD-2 includes a mute function, perfect for quiet tuning and guitar changes during a set. Whether you're fingerpicking a delicate melody or strumming vigorously, this preamp helps maintain the integrity of your acoustic sound.

Key Features:

  • Advanced BOSS sound processing with Acoustic Resonance and Ambience controls
  • Notch filter for quick feedback reduction
  • Dual outputs: instrument-level for amps and balanced DI for PA systems
  • User-friendly interface with simple stompbox controls
  • Built-in mute function for guitar changes and tuning
  • Compact and durable design suitable for pedalboards

Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Boss AD-2 Acoustic Preamp.

Comparisons

  • AC-3 is noted for being effective when electric guitars aim to mimic acoustics, whereas AD-2 is better suited for enhancing piezo-equipped acoustics.

    Source
  • COSM modeling in AC-3 may lead to overly scooped EQ when paired with acoustic-electrics, especially when the pickup signal is also scooped.

    Source
  • The Fishman Aura Spectrum, favored for its impulse response feature, is suggested over the AD-2 for those prioritizing nuanced acoustic tones.

    Source

Features and functionality

  • AD-2 includes a mini reverb and a notch filter, enhancing plugged-in acoustic sound quality.

    Source
  • The AD-2 can function as a DI with the option to output with or without applied ambiance (reverb).

    Source
  • The Boss AD-2 pairs effectively with a GE-7 Equalizer, allowing users to fine-tune frequencies without redundancy.

    Source

Use cases and applications

  • AC-3 can cause feedback and an unpleasant top end when used with acoustics at living room volumes.

    Source
  • The AD-2's reverb is subtle, potentially requiring a dedicated reverb pedal for more variety, especially if layering effects.

    Source
  • Log Jam Prolog stompbox may require a DI or an "instrument" level input on the mixer for optimal sound quality.

    Source
  • Boss RV-6 and Strymon Cloudburst reverb pedals are recommended complements for acoustic setups alongside the AD-2, enhancing atmospheric sound.

    Source

Setup and maintenance

  • Placing the harmony pedal before the AD-2 is recommended to ensure proper harmony detection.

Critic Reviews

Boss AD-2 Acoustic Preamp review | MusicRadar

musicradar.com

The Boss AD-2 Acoustic Preamp offers decent features but falls short compared to some rivals. While it effectively warms high-end tones and includes useful reverb and notch filter controls, it lacks EQ controls and its processing feels less organic than competitors. Ideal for mellow solo players but not a standout performer.
