Acoustic Combo Guitar Amplifiers

Natural Tone, Clear Sound, Performance Ready

A great acoustic amp delivers more than just volume. Look for clean headroom to avoid unwanted distortion, full-range speakers (often with tweeters) for capturing high-frequency detail, and EQ specifically voiced for acoustic instruments. Many feature built-in digital effects like reverb and chorus to add polish, plus essential anti-feedback tools (like notch filters or phase switches) for smooth stage performance. Models like the popular Fishman Loudbox series or Fender Acoustasonics often include dual channels with dedicated mic inputs, making them ideal all-in-one solutions for singer-songwriters.

Key Acoustic Amp Features:

• Clean Power Section: High headroom to prevent distortion.
• Full-Range Speakers: Woofer and often a tweeter for clarity.
• Acoustic-Voiced EQ: Controls tailored for acoustic frequencies (e.g., Mid scoop).
• Built-In Effects: Reverb and Chorus are very common.
• Feedback Control: Notch Filter and/or Phase Switch.
• Multiple Channels: Separate inputs for instrument and microphone (XLR input with phantom power common).
• DI Output: Balanced XLR out for connecting to a PA system.
• Aux Input: For connecting media players for practice.
• Portability: Often designed to be relatively lightweight and compact.

What are the pros and cons of using an Acoustic Amp vs. going direct to a PA?

• Pros: Acoustic Amp - On-stage sound control/monitor, tailored EQ/effects for acoustic tone, feedback control features, all-in-one solution for small gigs/singer-songwriters; Direct to PA - Utilizes larger PA speakers for wider coverage, potentially simpler setup if PA is already present, less gear to carry (if using house PA).
• Cons: Acoustic Amp - Limited coverage for larger venues (often needs DI out to PA anyway), another piece of gear to carry; Direct to PA - Relying on house PA/sound engineer for tone/monitoring, fewer dedicated acoustic features (EQ/feedback control might be generic on mixer).

Why can't I use an electric guitar amp for my acoustic guitar?

Electric guitar amps are designed to shape and often distort the signal, adding their own character (overdrive, specific EQ voicing). Plugging an acoustic guitar (especially one with a pickup) into one usually results in a harsh, unnatural, and often feedback-prone sound that doesn't represent the instrument's true tone. An acoustic amp provides clean amplification and preserves the acoustic character.

Do I need an acoustic amp if I have a PA system?

Not necessarily, but it offers advantages. An acoustic amp gives you immediate control over your tone and volume on stage (acting as your personal monitor) and provides features specifically designed for acoustic instruments (like feedback control). You can then send a signal from the amp's DI output to the main PA for audience coverage. For small venues or solo gigs, the amp might be all you need.

What features are important in an acoustic amp for singer-songwriters?

Look for dual channels (one for your instrument, one with an XLR input for your vocal microphone, preferably with phantom power). Independent EQ controls for each channel are crucial. Built-in reverb that can be applied to both channels is also very useful for adding polish to both vocals and guitar. A DI output is important for connecting to larger sound systems when needed.
