The Complete Guide to Acoustic Pickup
An acoustic pickup captures your guitar's authentic tone and lets you amplify it without a microphone. Discover different pickup types, installation options, and how to choose the right system for gigging or recording.
An acoustic pickup transforms your acoustic guitar into an instrument capable of plugging into amplifiers and recording equipment, preserving the natural tone of your instrument without requiring a microphone. Whether you're a busker amplifying your sound outdoors, a touring musician needing reliability on stage, or a home recordist capturing acoustic tones directly into your computer, understanding acoustic pickup types and installation is essential for anyone wanting to electrify their acoustic guitar responsibly.
What Is an Acoustic Pickup?
An acoustic pickup is a device that captures the vibrations of an acoustic guitar's strings and body, converting them into an electrical signal suitable for amplification or recording. Unlike electric guitar pickups (which sense magnetic field changes), acoustic pickups typically use piezoelectric sensors or microphone elements to detect actual physical vibration.
The central challenge in acoustic pickup design is capturing the guitar's full tonal character — its body resonance, natural reverb, and midrange warmth — without adding unwanted feedback, hum, or tonal colouration. Quality acoustic pickups achieve this delicate balance, letting you amplify acoustic tone that sounds authentically acoustic.
Types of Acoustic Pickups
Several acoustic pickup technologies dominate the market, each with distinct characteristics:
| Type | Technology | Sound Character | Pros & Cons |
|---|---|---|---|
| Piezoelectric (undersaddle) | Crystal sensor under the saddle | Bright, defined, articulate | Pro: Clean signal. Con: Thin midrange, can sound brittle |
| Piezoelectric (transducer) | Sensor glued to guitar body | Warm, resonant, body-focused | Pro: Natural tone. Con: Feedback-prone, variable installation |
| Soundboard transducer | Glued to inside of soundboard | Very warm, intimate, natural | Pro: Authentic tone. Con: Requires internal installation, permanent |
| Magnetic (rare) | Magnetic coil like electric pickups | Bright, definition-focused | Pro: Minimal feedback. Con: Weak bass, unnatural tone |
| Clip-on microphone | Tiny condenser mic on soundhole or body | Natural, full-spectrum, realistic | Pro: Portable, authentic. Con: Feedback risk, external |
Undersaddle piezoelectric pickups are the most common, offering a good balance between signal quality and affordability (£50–£300). Professional touring musicians often prefer dual-system pickups combining undersaddle piezos with body transducers or microphones for tonal richness. Clip-on microphones appeal to players prioritizing authenticity and portability over simplicity.
Installation Options
Acoustic pickup installation ranges from non-invasive (clip-on mics) to permanent (internal soundboard transducers). Your choice depends on your guitar, your plans for the instrument, and how much tonal compromise you'll accept.
Non-invasive options — clip-on mics and external transducers — require no modification. You can remove them whenever you want. This appeals to players renting guitars, using multiple instruments, or preferring to preserve their guitar's original state.
Undersaddle piezo pickups require bridge replacement or saddle modification. Most luthiers can install one in an hour. Once installed, they're permanent but deliver reliable, consistent signal with minimal feedback risk.
Internal soundboard transducers and dual-system pickups require routing inside the guitar body and usually demand a professional luthier's expertise. They're invasive but deliver the most natural tone because they sense the entire soundboard's resonance.
Feedback and Acoustic Pickup Performance
Acoustic guitars amplified through loud speaker systems risk feedback — that squealing howl that happens when amplified sound feeds back into the microphone or pickup. Quality acoustic pickups are designed to minimize feedback through directional sensitivity and frequency shaping.
Feedback management relies on several factors: pickup placement (body transducers are feedback-prone; undersaddle pickups are more feedback-resistant), amplifier placement (keep speakers behind or to the side of the guitarist, never in front), and onboard preamp quality. Many modern acoustic pickups include preamps with feedback suppressors or notch filters to address problematic frequencies.
Popular Acoustic Pickup Systems
Several manufacturers dominate the acoustic pickup market. LR Baggs is renowned for undersaddle systems and dual-pickup combinations, offering solutions from budget-friendly to professional touring-grade. Fishman systems are popular for their natural tone and integrated electronics. K&K Sound makes clip-on and internal transducers beloved by players prioritizing acoustic authenticity. Takamine and Yamaha manufacture integrated pickup systems in their production acoustics.
Choosing an Acoustic Pickup
Start with your intended use. Buskers and casual gigging benefit from budget undersaddle piezo systems (£50–£150) offering adequate signal and feedback resistance. Recording and serious gigging deserve mid-range systems (£200–£500) with onboard preamps, EQ, and feedback management. Professional touring musicians often invest in dual-system high-end pickups (£500+) combining multiple sensing technologies for tonal richness.
Before purchasing, consider whether your guitar is worth modifying (vintage or sentimental guitars deserve external solutions) and whether you'll use the pickup regularly. A clip-on mic might serve occasional busking perfectly well but may frustrate a touring musician needing rock-solid reliability.
Installation and Setup
DIY installation is possible for clip-on mics and external transducers but risky for anything requiring bridge work or internal installation. A professional luthier ensures proper installation, optimal positioning, and minimal damage to your guitar. Most professional installations cost £50–£200 in labour — money well spent for preserving your instrument.
The Bottom Line
An acoustic pickup lets you amplify your acoustic guitar responsibly, capturing its authentic character whilst gaining the flexibility to gig and record through amplification. Choosing the right pickup technology and installation method for your instrument, playing style, and needs ensures you preserve acoustic tone whilst embracing modern amplification possibilities.
