Best Pedals for Acoustic Guitars: Preamps, Reverb and Feedback Control

The best pedals for acoustic guitars are preamp and DI pedals with a notch filter, such as the L.R. Baggs Para Acoustic D.I. and the Fishman Platinum Pro EQ/DI, followed by a dedicated acoustic reverb such as the L.R. Baggs Align Reverb. Acoustic guitars have different needs from electrics: a piezo pickup wants a high-impedance input, the body wants to feed back at certain low frequencies, and the amp or PA wants a clean balanced signal. A good acoustic pedal solves those three problems first and adds effects second.

Key takeaways

• Put a preamp or DI first in the chain; effects like reverb go after it, not before.
• A notch filter and a phase switch are the two controls that fight feedback best, so look for both.
• Check the input impedance if you use a piezo pickup; published specs for the pedals below range from 2.2 megohms to 10 megohms.
• Decide whether you need an XLR output for a PA or only a 1/4-inch output for an amp.

Quick Comparison: Best Pedals for Acoustic Guitars

Why Acoustic Guitars Need Different Pedals

An electric guitar’s magnetic pickup produces a strong signal that most pedals expect. A piezo undersaddle pickup, the type fitted to most acoustic-electric guitars, produces a weaker and more brittle signal that wants a very high input impedance. Plug it into a pedal with a low input impedance and the tone loses body and turns quacky. Several of the pedals below publish their impedance because of this.

The second difference is feedback. A hollow body vibrates and couples to the amp or monitor, and the problem usually shows up as a boomy low-frequency howl rather than a high squeal. An acoustic pedal gives you a notch filter to remove that single frequency and a phase switch to flip the signal polarity when the speaker is fighting the strings.

The third difference is destination. A guitar going to a small acoustic amp is fine with a 1/4-inch output. A guitar going to a PA wants a balanced XLR DI output, ideally with a ground lift to stop hum. That is why most picks here have an XLR out and why we list outputs in the table.

How We Chose These Pedals

This is a research-based guide, and we did not personally use these pedals. We drew on maker specification pages, retailer descriptions, and published magazine and forum discussion. We looked for pedals that:

• Offer at least one practical feedback tool (a notch filter, a phase switch, or both).
• Publish clear specifications for outputs and power.
• Represent a spread of jobs: preamp and DI, a two-channel unit, a compact stage pedal, a reverb, and a budget all-in-one.
• Have a long retail history, so manuals and advice are easy to find.

The Order to Put Acoustic Pedals in Your Signal Chain

Because acoustic signals are delicate, the order matters more than it does on an electric pedalboard. A practical order is:

1. Tuner (muting). First or built into the preamp, so you can tune silently on stage.
2. Preamp or DI. Sets impedance, gain, EQ, notch, and phase. Everything after it works with a healthy signal.
3. Compressor, if separate. Evens out strumming dynamics before time-based effects.
4. Reverb or delay. Time-based effects come late so the repeats are not squashed or filtered again.
5. DI box or direct output. The final stage before the PA or amp.

Some preamps, including the Fishman Platinum Pro and the L.R. Baggs Para DI, have an effects loop so you can put a reverb between the preamp stage and the DI output. That keeps the PA signal clean and the reverb in its proper place in the chain.

1. L.R. Baggs Para Acoustic D.I.: Best Preamp and DI for Precise EQ Control

• 5-band tone control: bass, sweepable mid, presence, treble, tunable notch
• Notch about 98 Hz to 247 Hz; mid about 400 Hz to 1.6 kHz
• Phase switch, input gain, fixed low-cut, effects send and return
• 48V phantom power or 9V battery (about 200 hours listed)

Best for: Gigging players who want to shape tone before the sound engineer sees it. The sweepable mid and notch let you carve problem frequencies quickly.

Skip if: You want built-in compression, a tuner, or a footswitchable boost. The Para DI has none of those.

Pros:

• Both XLR and 1/4-inch outputs
• Phantom power option means no battery changes
• Compact enough for a pedalboard
• Strong feedback toolset

Cons:

• No tuner or compressor
• Controls take some learning for beginners

2. Fishman Platinum Pro EQ/DI: Best All-in-One Stage Preamp

• Discrete Class A preamp, 5-band EQ with sweepable mid
• Sweepable notch filter, phase invert switch, adjustable low-cut
• Analog soft-knee compressor, effects loop, chromatic tuner, footswitchable boost
• Balanced XLR DI with pre/post EQ switch and ground lift; 9V battery or Fishman 910-R supply

Best for: Solo performers who want one pedal to handle EQ, compression, tuning, and a clean DI feed to the PA.

Skip if: You need phantom power or a very small footprint. One published comparison notes that the Fishman has no phantom option, and it is larger than most.

Pros:

• Built-in compressor and tuner in one box
• Effects loop for a reverb or delay
• Footswitchable volume boost for solos
• Mode switch tailors EQ for different instruments

Cons:

• Plastic-feeling build, according to one reviewer
• Power supply is sold separately
• Notch knob is marked in notes rather than frequency, per one reviewer

3. BOSS AD-2: Best Compact Pedal for a Small Pedalboard

• Controls: Acoustic Resonance, Ambience, Notch
• Acoustic resonance modelling for tone shaping, with subtle reverb ambience
• Two outputs: amp output and a balanced 1/4-inch TRS line out for the PA
• Hold-to-mute footswitch, buffered bypass, 9V battery or adapter

Best for: Players who want a simple, small pedal with three knobs that handles the basics: tone shaping, a touch of reverb, and a notch for low-frequency feedback.

Skip if: You need a full parametric EQ or a true XLR output. The AD-2 line out is a 1/4-inch TRS jack, not XLR.

Pros:

• Very simple controls
• Mute footswitch for quiet tuning
• Two independent outputs for amp and PA
• Runs on a battery

Cons:

• Single notch knob without frequency readout
• Limited EQ compared with larger pedals

4. BOSS AD-10: Best for Two Pickups or Two Guitars

• Two input channels, each with an independent 4-band EQ
• Variable low-cut, multi-band compressor, anti-feedback with two notch filters
• Ambience, delay, chorus, boost, 10 memory slots, and an 80-second looper
• Stereo XLR and stereo 1/4-inch outputs, plus USB audio; power supply included

Best for: Players with a guitar that has two pickups, or players who swap between two instruments in one set. It blends the pickups separately before they hit the PA.

Skip if: You want a small board. It is a floor workstation rather than a compact stompbox, and the menu has more depth than most solo players need.

Pros:

• Independent EQ and compression per channel
• USB lets you record directly to a computer
• Memory slots recall settings between songs
• Looper for solo performance

Cons:

• Larger and heavier than a compact preamp
• More controls to learn

5. Radial Tonebone PZ-Pre: Best Two-Channel Preamp for Piezo Signals

• Two inputs, each with its own level control and piezo buffer
• Buffer input impedance listed at 10 megohms
• Bass, treble, and a semi-parametric mid sweeping about 82 Hz to 5.6 kHz
• Notch filter about 56 Hz to 330 Hz, low-cut at 75 Hz or 220 Hz, 180-degree polarity switch
• Pre-EQ DI out, post-EQ DI out, tuner out with mute; needs a 15V DC supply

Best for: Players who use a piezo-equipped acoustic and want the cleanest signal path, or those who blend two sources such as piezo and soundhole pickup.

Skip if: You want a lightweight pedal with a battery. The PZ-Pre needs a specific 15-volt supply and sits at the upper end of this list for size and cost.

Pros:

• Two separate DI outs for front-of-house and monitor feeds
• Very high buffer impedance for piezo pickups
• Notch range reaches into the low frequencies where feedback is worst
• Rugged build

Cons:

• Needs a 15V supply (check what is included)
• Large footprint
• No built-in reverb or compressor

6. L.R. Baggs Align Reverb: Best Dedicated Acoustic Reverb

• Controls: decay, reverb amount, tone, volume
• Single reverb effect, mono only
• 2.2 megohm input impedance
• True bypass; 9V battery or 9V DC

Best for: Players who already have a preamp and want a simple, natural reverb tuned for acoustic pickups.

Skip if: You want a shimmer, a spring, or a stereo option. Forum users confirm there is no shimmer mode, and it has no stereo outputs.

Pros:

• Four knobs and no menu
• Designed with acoustic pickups in mind
• True bypass keeps the signal clean when off
• Battery option

Cons:

• Only one reverb voice
• No stereo outputs

7. SONICAKE A Factory: Best Budget Preamp and Reverb in One Box

• Analog preamp plus digital reverb
• 3-band EQ and a notch filter with adjustable gain and frequency range
• Mute function; XLR balanced output with ground lift
• 10 megohm input impedance; 9V center-negative supply, about 60 mA, not included

Best for: Budget-conscious players who want a preamp, notch, and reverb in a single box and who need an XLR out for a small PA.

Skip if: You need a long track record or a heavy-duty metal chassis. It is a newer design from a budget-focused brand.

Pros:

• Preamp, notch, and reverb in one pedal
• XLR with ground lift
• High input impedance suited to piezo pickups
• Low entry cost

Cons:

• Power supply not included
• Fewer EQ and routing options than the premium picks

Also Consider

• Fishman AFX AcoustiVerb Mini: A compact acoustic reverb pedal that suits a crowded pedalboard.
• TC Electronic Hall of Fame 2: A versatile reverb with room, hall, spring, and other modes if you want more than a single acoustic voice.
• Radial Tonebone PZ-Deluxe: A single-channel preamp from the same maker with a boost and a simpler layout.
• GOKKO GK-32 SpanishFly: An inexpensive preamp and DI pedal with anti-feedback and treble controls for experiments.

Buying Guide: How to Choose Pedals for Acoustic Guitars

Start with your pickup type

A piezo undersaddle pickup needs a high input impedance. As a rule of thumb, look for 1 megohm or more, and published specs for this list run from 2.2 megohms (Align Reverb) to 10 megohms (Radial PZ-Pre buffer and SONICAKE A Factory). A soundhole magnetic pickup is less demanding, and a microphone-based system often has its own preamp. If you are not sure, check the pickup maker’s manual.

Choose your feedback tools

• Notch filter: Removes a narrow band. Aim for a range that covers about 80 Hz to 250 Hz, where most body feedback sits. The Baggs Para DI (about 98 Hz to 247 Hz) and the Radial PZ-Pre (about 56 Hz to 330 Hz) are good examples.
• Phase switch: Inverts polarity. Flip it when the PA monitor and your guitar are fighting; one position will usually sound fuller and feed back less.
• Low-cut: Cuts rumble below a set frequency. A fixed 80 Hz to 100 Hz low-cut helps most stage setups.

Match outputs to your destination

If you play through an acoustic amp, a 1/4-inch output is fine. If you play through a PA, an XLR DI output with a ground lift is cleaner and more reliable over longer cables. A pedal with both lets you send a clean feed to the PA and a different signal to your monitor.

Think about power

Batteries are convenient for casual gigs, but each pedal draws different current. The Para DI lists about 200 hours from a 9V battery, while the SONICAKE draws about 60 mA, which would drain a battery quickly and wants an adapter. Phantom power (Baggs) is attractive if you play through a mixer with phantom available. For a regular board, buy one isolated power supply and standardise.

Decide how many effects you really need

Acoustic playing usually benefits from three things: a clean preamp, a small amount of reverb, and sometimes light compression. Chorus and delay are optional. Overloading the signal chain with effects makes feedback harder to control, so add them one at a time.

Budget by job

1. A compact preamp or all-in-one is enough for open mics and coffee shops.
2. A full preamp/DI with a compressor and tuner suits regular solo gigs.
3. A two-channel unit pays off once you use two pickups or two guitars.
4. A separate reverb is the last purchase, not the first.

Matching a Pedal to Your Pickup and Your Stage

A Simple Soundcheck Routine for Acoustic Pedals

Pedals only help if you set them in a sensible order. This routine takes about five minutes and works with most of the preamps above.

1. Start flat. Set every EQ knob to the middle, the notch to its lowest-effect position, and reverb off. Bring the guitar up until it is at a comfortable volume.
2. Set input gain so the loudest strum does not clip. If the pedal has a clip light, a brief flicker on your hardest chord is enough; a steady light means you need to turn it down.
3. Find the feedback. Turn the monitor up to stage volume, strum an open low chord, and note whether a particular note howls. That is the frequency to notch.
4. Sweep the notch slowly. Start with the knob fully off and turn it until the howl stops. Narrower is better; a wide notch thins out the low end.
5. Try the phase switch. Press it once and listen. If the guitar sounds fuller or the howl drops, leave it there.
6. Add the low-cut. Roll off the rumble below about 80 Hz if the PA is boomy, but stop when the body of the guitar starts to disappear.
7. Add reverb last. Use just enough that the guitar feels part of the room. Too much will smear picking detail and raise the chance of feedback.

Take a photo of the knob positions for each venue. Acoustic setups change with room size, monitor placement, and strings, so having a reference makes the next soundcheck faster.

Common Problems and Quick Fixes

Frequently Asked Questions

Do I need a preamp pedal for an acoustic-electric guitar?

Not always, because many acoustic-electrics have a built-in preamp. But an outboard preamp usually gives better EQ control, a notch filter, and a cleaner DI output. If your onboard preamp works for you, a pedal is optional.

What is the best pedal for acoustic guitar feedback?

A preamp with a sweepable notch filter and a phase switch is the usual answer. The Baggs Para DI, the Fishman Platinum Pro, and the Radial PZ-Pre all provide both, and the BOSS AD-10 adds an anti-feedback function that seeks out the offending frequency.

Can I use electric guitar pedals with an acoustic?

Yes, but with care. Pedals designed for magnetic pickups may have low input impedance that dulls a piezo signal. Put a high-impedance preamp first, and keep gain-heavy pedals away from the signal.

Which reverb is best for acoustic guitar?

A natural room, plate, or hall setting with moderate decay usually sounds best. The L.R. Baggs Align Reverb is built for acoustic pickups, while the TC Electronic Hall of Fame 2 offers more variety if you want to experiment.

Do I need an XLR output?

Only if you plan to connect to a PA or mixer. XLR is balanced, so it carries signal over long cables with less noise. For home or amp-only use, a 1/4-inch output is enough.

Is phantom power safe for acoustic pedals?

Phantom power is a standard 48V supply from a mixer and is safe for equipment that is designed for it, such as the Baggs Para DI. Do not connect it to a pedal that is not rated for phantom power. Check the manual first.

How many pedals does an acoustic player really need?

Many players use one preamp pedal and one reverb. A compressor is useful for strumming, and a tuner is essential. Anything beyond that is a matter of taste.

Which One Should You Buy?

• Best overall preamp and DI for the gig: L.R. Baggs Para Acoustic D.I., or the Fishman Platinum Pro EQ/DI if you also want compression and a tuner.
• Smallest board: BOSS AD-2.
• Two pickups or two guitars: BOSS AD-10 or Radial Tonebone PZ-Pre.
• Natural reverb on top of a preamp: L.R. Baggs Align Reverb.
• Tightest budget: SONICAKE A Factory, with a separate power supply.

A sensible first purchase is a preamp with a notch and an XLR output. Buy effects after you have learned what your guitar does in a room.

If you are still unsure, ask which problem you actually have today. A guitar that howls through the monitor needs a notch and phase switch. A guitar that sounds thin through a pedalboard needs a high-impedance buffer first in the chain. A guitar that sounds fine but dry needs reverb. Fix the first problem on that list before adding anything else, and the rest of the signal chain becomes much easier to build.
