Should You Use a Pickup on Your Acoustic Guitar?

The Real Question: Why Do You Need to Amplify?

The decision to install a pickup on an acoustic guitar depends entirely on the use case. Players who only perform in rooms under 30 people can skip pickups and rely on a microphone or acoustic projection alone. Players who gig regularly in venues above 80 capacity need a pickup because no unamplified acoustic cuts through a drum kit or a bar crowd. The border case, 30 to 80 capacity, is where the decision gets interesting.

I have installed pickups in roughly 400 acoustics at the Strum Avenue bench since 2012, and the single most common regret is players who paid for a pickup they never actually used live. If you gig fewer than 6 times a year, rent or borrow an amplified guitar for those gigs and leave your primary instrument untouched.

The Four Pickup Types and Their Strengths

Under-saddle transducers like the Fishman Matrix Infinity ($180 installed) sense string motion through pressure on a thin strip under the saddle. They are feedback-resistant, balanced across strings, and produce a clean but 'quacky' compressed sound. Best for singer-songwriters who prioritize feedback-free live performance over natural tone.

Soundhole magnetic pickups like the LR Baggs M80 ($275) clip into the soundhole and sense string vibration magnetically. They sound warmer than under-saddle transducers and can be removed without modification. Internal microphones like the DPA 4099G ($600) clip inside the body and sound the most natural but feed back at high stage volumes. Blended systems like the LR Baggs Anthem combine a saddle pickup with an internal mic for studio-quality live sound.

What Pickups Do to Your Tone

Every pickup compromises acoustic tone in predictable ways. Under-saddle transducers dampen the saddle's natural resonance by 2 to 4 percent, producing the compressed 'piezo quack' that recording engineers hate. Soundhole pickups add about 60 grams of mass to the top, measurably reducing high-frequency response. Internal microphones pick up body noise and breathing but preserve natural tone best.

For most players, the acoustic tone penalty is less important than the live amplification benefit. A Taylor 814ce with ES2 electronics sounds 5 percent less lively unplugged than the same guitar without electronics, but it sounds 200 percent better through a PA. The trade is usually worth it.

Installation: DIY vs Professional

Soundhole pickups like the LR Baggs M1 and Fishman Rare Earth install in 15 minutes with no modification, just clip them into the soundhole, route the cable through a small hole drilled in the end block, and you are done. Drilling the end block hole is the only permanent modification, and it costs $40 at most shops.

Under-saddle and internal systems require more work. Removing the saddle, routing slots in the bridge, installing the transducer and preamp, and drilling the end pin jack take a luthier 90 minutes to 2 hours. Expect $150 to $250 for installation plus the pickup cost. Martin and Taylor factory systems installed from new are already done for you.

Cost-Benefit Analysis for Gigging Players

A working singer-songwriter gigging 40 nights a year in clubs between 100 and 400 capacity will benefit immediately from a quality pickup. A Taylor 814ce with factory ES2 costs about $2,700 and comes ready to plug in; a Martin D-28 plus a Fishman Matrix install totals about $3,050. Both are investments that pay back within a year for a working performer.

A hobbyist who plays 3 or 4 times a year at coffee shops is better served by a clip-on pickup that costs $150 and requires no modification. Permanent installs are not reversible, and a $200 pickup in a vintage guitar can reduce resale value by $400 to $800. Always ask: is this guitar destined for stage work, or is it a home instrument?

The Microphone Alternative

For quiet venues, acoustic festivals, and recording sessions, a microphone on a stand still outperforms any pickup. A Shure SM57 placed 20cm from the 12th fret captures the natural character of the guitar in a way no pickup can match. The trade-offs are mobility (the mic has to stay in front of the soundhole) and feedback risk at high stage volumes.

Many touring performers use both: a pickup for most of the set and a dedicated microphone on a separate channel for solo acoustic songs. The mic runs muted until needed and comes in during the quieter numbers. This approach gives you the best of both worlds at the cost of one extra mic stand and one PA channel.
