Electronics and amplification. Plugging your acoustic in.

You’ve found the perfect acoustic guitar: the right wood, the right feel, the right tone, and even the ideal case to keep it safe. You’re strumming away, enjoying that pure, resonant, unplugged sound.

But at some point you’ll likely want to be heard beyond your living room: whether that means playing with a band, busking on a street corner, or recording a demo. This is where electronics and amplification come into play.

Suddenly, that beautiful wooden instrument needs to connect to an amplifier or a PA system. This isn’t as simple as just plugging in a cable; the way your acoustic guitar captures its sound and transmits it can significantly affect its amplified tone.

In this section we’ll demystify the pickups, preamps, and various systems that let your acoustic truly shine, loudly and clearly, in any performance or recording setting. Get ready to plug in!

Pickup systems.

Preamps and controls.

What is a preamp in the context of an acoustic guitar? Imagine your pickup (whether it’s under the saddle, a mic, or a soundboard transducer) is whispering its signal. That whisper is far too weak, and sometimes a bit tonally wonky, to be heard clearly by an amplifier or PA. The preamp is the unsung hero that takes that tiny, delicate signal and does two main things.

It boosts it: amplifying that whisper into a proper “line level” signal, strong enough for an amp or mixing board to actually hear and work with. Without this boost, you’d get a super quiet, often noisy sound.

And it shapes it: most preamps include some form of EQ (bass, mid, treble) and sometimes a tuner, phase switch, or notch filter. This lets you fine-tune your amplified tone, cut nasty feedback frequencies, and generally make your guitar sound its best when it’s plugged in.

You’ll typically find preamps either built right into the guitar’s side (those little boxes with sliders and knobs), or as external units, sometimes in pedal form, that you plug into before your amp or PA.

Acoustic amplifiers.

Dedicated Acoustic Amplifiers

Characteristics:

• Designed specifically for acoustic instruments
• Flat frequency response (unlike electric guitar amps)
• Often include feedback suppression features
• Many include effects like reverb and chorus

Recommended brands:

• AER
• Fishman
• Bose
• Boss/Roland
• Fender Acoustic Series

PA Systems

Best for:

• Larger venues
• Full band situations
• When singing and playing

Advantages:

• Handles full frequency range
• Can accommodate multiple instruments
• Designed for whole venue coverage

Considerations:

• Requires a DI box for best results
• May need monitor for hearing yourself
• Less portable than dedicated amps

Recording options.

Direct Recording

Method: Plugging your guitar’s pickup system directly into an audio interface.

Pros:

• Simple, easy setup
• No microphone bleed or room noise issues
• Convenient in home studio environments

Cons:

• Rarely captures the full acoustic character of the guitar
• May sound sterile or artificial without proper processing

Microphone Recording

Popular microphone choices:

• Small-diaphragm condensers (Neumann KM184, AKG C451)
• Large-diaphragm condensers (AKG C414, Neumann U87)
• Ribbon microphones (Royer R-121, AEA R84)

Common microphone placements:

• 12th fret (balanced tone)
• Near the bridge (brighter, more articulate)
• Neck joint (warmer, fuller)
• Room microphones (for ambience)

Acoustic-electric vs retrofit.

Factory Acoustic-Electric

Advantages:

• Integrated, often aesthetically pleasing design
• Pickup system optimized for that specific guitar
• No modification required

Disadvantages:

• Limited to the installed system
• Often more expensive than non-electric equivalent
• Can’t easily try different pickup types

Aftermarket Pickup Installation

Advantages:

• Can choose from many pickup types
• Can add electronics to your favorite guitar
• Often less expensive than buying a new acoustic-electric

Disadvantages:

• May require permanent modification to your guitar
• Installation quality depends on the technician
• Might affect the guitar’s acoustic tone or appearance

Electronics comparison chart.

Not all acoustic pickup systems are created equal. Here’s how the five main types compare across the factors that matter most.

Choosing the right pickup. There’s no single “best” option, it depends on your situation. Playing live in loud environments? Prioritize feedback resistance. Recording in a studio? Go for natural acoustic sound. Want maximum flexibility without permanent modification? A magnetic soundhole pickup is your safest bet.
