The Best Acoustic Guitar Amps 2023

Best overall

Boss really went to town with this one; 60-watts and two-channels to provide the foundations for live flexibility, but where the Acoustic Singer Live really shines for us is with its sound performance and added features. And that’s down to some classic Boss innovation with the Acoustic Resonance feature that really does work in giving piezo pickups more of an ‘acoustic’ and high-fidelity sound. But there’s much more going on here for players and singers…

In addition to an onboard looper, there’s a Harmony function for the vocal channel that uses similar tech found in Boss’s VE-8 pedal. It creates vocal harmonies in either double or unison modes via real-time tracking of chords in the guitar input. It actually works without sounding like a gimmick and is great for solo performers looking for added dimensions in their performances.

We especially like the separate DI outputs for the vocal and guitar to send wet or dry signals for when you need to go to front of house. Boss has also included support for phantom power to make this a very well-considered option for function artists. And if you need even more headroom there’s the 120-watt Acoustic Singer Pro option too.  

Best premium option

This German brand is the go-to for one of the greatest acoustic players of all-time; Tommy Emmanuel. Jerry Douglas and Carl Verheyen are Compact 60 users too. The quality of performance here for the rest of us to enjoy is undeniable. It’s a pro’s choice in terms of build quality and our experience gigging with this amp as part of a four-piece in bars proved it’s a joy for all levels of player with high headroom with sublime clarity.

The Colour switch for a mid-cut and treble boost proves very useful as a quick alternative EQ mode that may be preferred for mellowing some mid-forward guitars. The Compact 60’s flexibility is also boosted by the ability to mount it on a stand for clearer monitoring.

The second channel offers a 2-band EQ and reverb for vocals, while the first offers 3-band and excellent onboard footswitchable reverb, chorus and delay if you don’t want to bring pedals into the equation. A real workhorse acoustic amp for the regular gigger.

Best for busking

Fishman’s Loudbox amp range has been relied on by performers for years and this one is aimed squarely at those that need the flexibility of playing away from a mains supply. While a lot of the competition may offer disposable battery power, it’s not sustainable and it adds significant cost over a product’s lifetime. Here we have a rechargeable internal battery on this 60-watt combo that will give you four hours on average at maximum volume and around 12 hours with volume at around half. 

The onboard reverb and chorus are most welcome, and combined with a three-band EQ and compact dimensions it’s an ideal option for buskers – or anyone who wants the flexibility to play through an acoustic amp anywhere. The 10-degree tilt should not be overlooked here, indeed we think the angled cab approach to design is a valuable feature for any guitar amp, because you need to hear it with your ears and not the backs of your legs.

For singers, the second channel here offers a two-band EQ with its own independent reverb, and the Bluetooth connectivity is a welcome feature for those performers who are playing to a rhythm or full backing track – wired auxiliary-in is also available. 

Best for gigging

A proven force in the electric guitar amp world, Blackstar’s move into acoustic was carefully considered and the British company brought virtuoso Jon Gomm into the design process. The result is a 120-watt amp with an impressive range of features for any gigging acoustic player, and a performance to match.

Gomm’s influence is reflected in the Sonnet’s extended sub response that’s ideal for the low-end needs of percussive styles using body-sensor pickups. For the piezo players there are High Pass Filter (HPF) and Brilliance controls to dial in your high end, that’s detailed without becoming harsh. 

Reverb is an essential effect for acoustic to add ambience and the Sonnet is a treat with four different types, and separate levels for each of its two channels. Phantom power also means condenser mic input is welcome here. A tilt stand also allows the Sonnet to be heard more clearly as an onstage monitor with your mix being sent to the sound desk via XLR, rounding out an excellent gigging acoustic combo amp.  

Best pedal amp

Another great name in acoustic analog preamps follows up its pro-grade Spectrum Aura pedal but loses the acoustic imaging feature that was beneficial in giving piezo pickups more of a mic’d character. Nevertheless, there are plenty of very useful features on offer here to shape your tone going into a PA or your own FRFR cab for live performance – including an onboard one-knob soft-knee compressor, chromatic tuner, sweepable notch filter, five-band EQ and switchable EQ modes for guitar and bass. 

A discrete Class-A preamp offers high fidelity and headroom here, with an onboard boost for when you need more. That compressor is a big plus here, offering subtle softening of dynamic peaks to mellow out harder strumming and reduce the risk of ear fatigue for your audience! 

The two-control mid section of the EQ allows players to hone in on a frequency range and boost or cut it to taste – vital for making sure your guitar is vibrant in the mix, while the Brilliance knob can help reduce finger noise and buzz. An impressive package, and choosing between this and the Baggs (below) may come down to how important onboard compression is for you. 

Best for home

If you’re looking for a do-it-all modeling amp for acoustic, electric, and bass needs that you can learn and gig with, the Spark 40 is in a class of its own. Of the 33 available amp models, four are dedicated to acoustic guitar with over 40 different effects on tap including multiple reverbs and delays. There’s a lot of inspiration here and the Positive Grid’s BIAS modeling engine consistently impresses.

The tones are only part of the package; streaming Bluetooth audio to the Spark is a breeze, and the Spark app allows you to download a host of Tonecloud sounds from other users, transcribe the chords for any song you can find on YouTube, and jam with backing tracks. 

Spark 40 is currently the biggest model in the three-amp Spark lineup alongside the 10-watt Spark Mini and pocket-sized Spark Go and offers the most hardware controls over gain, reverb, and delays. There are also four onboard presets to save your favorite tones.

LR Baggs is a formidable name in acoustic guitar pickup systems, but it’s also long been a trusted brand for DI and floor-based preamps for pros with its Para DI. And this is its best pedal for live players yet because it includes everything you’ll need to play through a PA while shaping and enhancing your tone.

A five-band EQ gives you more detailed editing than even most amps; the low and high-mid controls are especially important in dialing in a sympathetic tone for your piezo without getting too muddy or brash. Onboard phase inversion and a Garret Null notch filter help tackle feedback fast, and we especially like the footswitchable volume boost (up to 9dB) for extra clout in band scenarios.

But there’s more! An onboard tuner means one less pedal to take, and the Venue’s series FX loop means you can get optimum clarity from your reverb and delay effects. Its audio transformer-coupled output offers complete isolation to eliminate ground loop noise – it’s reassuringly quiet in use as a result – and players can run the ¼ inch output simultaneously via an XLR output to PA if they want to bring their own active speaker monitor to shows. 

Why should electric guitar players have all the fun? The Helix Stomp is one of the best value multi-effects and amp modelers around for features and superb tones – it continues to be well-supported with excellent firmware updates too. Its flexibility means it can be used as an excellent acoustic preamp and IR loader, as well as for electric guitars; so if you use both in your live sets, say hello to your new portable best friend.

The 23 onboard reverb algorithms offer some lush ambient sounds to give your acoustic tone wider horizons, and the onboard LA Studio compressor can smooth out your extremes. The Studio Tube Pre and Songwriter patch are great options to start with and fine-tune, with the Mic Preamp also a great addition to your chain for warmth, and then it’s just a matter of pairing with the cab IR model or EQ chain of your choice on the Helix before going out to a PA. But if you’re into using effects with your acoustic, the range and quality here is huge for experimentation and inspiration. 

Another great thing about the Helix for gigging players are the presets and Snapshots it offers. The latter can allow you to have different variations in levels and effects combinations with your core signal chain that you can bring in for the verse of a song, then switch to another for the chorus. 

A new 2023 model from Boss, the 10-watt, two-channel stereo AC-22LX can be powered by mains or 8 x AA batteries. The ace up its sleeve is a five-voice Air Feel mode; one dry and four based on emulating different mic’d recording set-ups to breathe more acoustic authenticity into piezo systems especially. It works well too, offering distinct options alongside reverb and chorus effects with a straightforward three-band EQ. 

Players can take advantage of the onboard looper and beats with a footswitch (sold separately) and there’s a separate channel with phantom power, two-band EQ and independent reverb for mics.  

We really like the wood-look of the casing of this amp and it performed very well with our Sigma dreadnought featuring the fairly budget Fishman Sonitone piezo system. The 10-watts means it’s good for intimate solo performance, but utilizing the output to a PA means the combo itself won’t be loud enough to act as a monitor in a band situation.
