Not all that long ago, guitar practice amps were just that – small, basic, standalone boxes with one or two channels, and a rudimentary reverb on-board – functional, but limited. However, recent years have ushered in a new era of ‘smart’ amps designed for home use featuring contemporary styling, expanded tonal options and comprehensive connectivity.

Leading the charge is arguably the Positive Grid Spark Mini: a small-format, portable practice amp packing in a lot of features including smartphone integration, Bluetooth, and handy jamming tools such as its Smart Jam (which analyses your playing to create a custom jam track) and Auto Chords (which can listen to a piece of music and figure out a chord chart for you). You can read our full Positive Grid Spark Mini review here.

While the Spark Mini wins in the popularity stakes, there are plenty of other contenders out there. We’ve handpicked out favourites here. And even better, they’re all currently discounted for Black Friday! Of course, if you like the sound of our review, the Spark Mini is also on sale with $40 for Black Friday.

1. Yamaha THR10II

Best for home use

Output: 20 watts | Amps: 6 guitar, one bass, one acoustic, flat | FX: 8 | Software: THR Remote (iOS/Android), Yamaha Rec’n’Share (iOS only) | Smart features: Bluetooth, USB audio interface, mobile editing | Power: Mains PSU

Stylish looks

Lots of sounds

Mobile editing

Bluetooth connectivity

USB recording

You’ll need to look to the THR Wireless range for cable-free guitar connectivity and battery power

With its THR series, Yamaha coined the ‘third amp’ phrase. That is, a dedicated amp to use at home, separate from your club-size combo or trouser-flapping tube stack. The second generation, THRII continues this, while also checking the visual boxes, with its non-offensive, stick-it-on-the-shelf looks and clean control layout. We get physical sound editing via five selectable amp models, channel controls for gain, EQ and volume, plus a pair of control knobs for selecting effects and reverb, and master controls for the guitar/audio outputs.

Bluetooth comes built-in, giving you a gateway to Yamaha’s THR Remote editor app for iOS and Android and iOS users can also download the excellent Yamaha Rec’n’Share app, which integrates your device’s camera for quick and easy creation of video clips.

Yamaha happens to own Cubase, and it’s bundled Cubase AI and Cubasis LE. So combined with the USB connectivity you’ll be able to record pro-sounding guitar tracks straight out of the box.

The THR has more than earned its reputation as a great-sounding amp since it first launched, and there’s plenty of additional smart features to get excited about here. If you’re happy to spend a bit more, check out the THRII 10W, which has a built-in receiver for a Line 6 Relay wireless transmitter (sold separately).

2. NUX Mighty Air

Best on a budget (oh, and it's pronounced ‘New-X’)

Output: 8 watts | Amps: 13 | FX: 28 | Software: NUX MightyAmp app | Smart features: Wireless guitar connection, Bluetooth, mobile app, USB audio interface | Power: Internal rechargeable battery

An impressive number of sounds and features at a low price

Product info is lacking a bit

NUX’s stock-in-trade is providing a killer set of features at a low price point, and the Mighty Air does exactly that. Come at it with a spec list and the Mighty Air stands tall: Bluetooth? Yes. A wireless input for your guitar? Absolutely! App control? That’s a yes too.

There’s plenty of control for using the amp in standalone mode, with three selectable channels, gain, volume, tone and delay/reverb knobs, plus you can start, stop and change rhythms from the internal drum machine (yep, it has one of those too).

Linking it up to the app is where the fun really lies though. Here, you get access to the full list of features that aren’t immediately visible from the Mighty Air’s control panel (or its marketing or manual). There are 13 amp models based on classics from Marshall, Mesa/Boogie, Fender, Diezel and more. In addition to this, it’s packing 20 multi-fx modes, four delay types and four reverbs along with 19 speaker impulse responses.

Delve a little deeper and you’ll uncover a metronome, jam tracks, and more, and it’s all really simple to operate with a clear presentation.

Finally, it’s worth noting that the Mighty Air can also use its USB socket as an audio interface (rather than simply for charging), which makes this a stone-cold bargain. The presentation might be slightly lost, but the Mighty Air lives up to its name and sounds great, especially for the money.

3. Blackstar ID:Core III 10

Best for stereo sound

Output: 10 watts | Amps: 6 | FX: 12 | Software: Blackstar Architect desktop editor | Smart features: USB audio, remote software editing, direct-to-phone audio connection | Power: Mains PSU

Excellent sound response

Plenty of tonal options

Architect editor

Phone/audio integration via a cable

No Bluetooth or mobile app

Blackstar recently upgraded its ID:Core series to its third generation, but in case you’re not already familiar, here’s what you need to know. ID:Core is Blackstar’s range of digital amps, as such, they’re loaded with all kinds of useful features including six preamp voices ranging from clean to heavy overdrive/distortion, and thanks to Blackstar’s patented ISF control, you can dial the amp’s tonality from US to UK flavours, and anywhere in between. There are effects, too, in the form of four modulation effect types, four delays and four reverbs.

There’s no Bluetooth (look at the Blackstar B.E.A.M. for that), nor is there mobile app integration, but things get smart when you start looking at the ID:Core’s other features. First up is the Architect software, which runs on a Mac and PC. This gives you deeper editing over your presets, with everything laid out clearly, and Architect also includes Blackstar’s CabRig Lite, which gives you control over virtual speaker cabs, mics and virtual room environments.

One of our favourite things about ID:Core though, is the immersive Super Wide Stereo sound, which really needs to be experienced to fully appreciate. ID:Core 10 also comes with a USB audio interface built-in, and Blackstar has added a direct-to-phone audio socket, so you can incorporate all of your tones into phone-captured videos with a simple cable.

4. Boss Dual Cube LX

Best for practicing anywhere

Output: 10 watts | Amps: 9 preamp types | FX: 8 | Software: Dual Cube LX mobile app (iOS/Android) | Smart features: Bluetooth (via optional dongle), USB audio interface, mobile app | Power: PSU or batteries

Lots of tonal options

Plenty of hands-on control

Battery power (8xAA)

No internal rechargeable battery

Bluetooth requires an additional dongle purchase

Likewise a footswitch for looper control

Boss’ Cube range of amps have been a common fixture on ‘must-try’ practice amps for decades. The Dual Cube LX brings the Cube format to your desktop with a range of features aimed at making practising anywhere more convenient. First, it’s loaded with Boss amp and effects models – including an on-board looper (you’ll need a footswitch to control it, though). There’s also plenty of control to hand, with selectors for amp and effects models, gain, volume and three-band EQ controls and more, plus it’s portable, and capable of running off batteries too (although this does require 8xAA batteries, so rechargeables are advisable).

But what of its smart capabilities? Well, while there’s a USB audio interface which also enables editing via a desktop app, the Dual Cube is best described as ‘smart ready’. That’s because its Bluetooth is provided by the Boss BT-Dual Audio/MIDI Bluetooth Adaptor – an additional purchase. Once you attach the dongle, you’ll be able to hook the amp up to your smartphone for control via the Dual Cube LX Editor app for iOS or Android. Here you can wirelessly delve deeper into the Dual Cube LX’s features when you’re away from a computer. It’s a great mid-point between the Spark Mini’s app reliance and the hands-on control of a traditional amp.

5. Positive Grid Spark GO

Best for flashes of inspiration

Output: 5 watts | Amps: 33 | FX: 48 | Software: Positive Grid Spark mobile app (iOS/Android) | Smart features: Mobile app editing/recall of patches, Smart Jam, Auto Chords, video capture (phone or tablet required) | Power: Internal rechargeable battery

Affordable

Portable entry point with unrestricted access to the Spark ecosystem

You’ll need to connect your phone almost constantly if you like editing your sound often

If you’re looking for Positive Grid’s stellar feature set in a more compact, portable and convenient format, look no further than the Spark GO. This is the most recent addition to the PG family, and as with the Spark and Spark MINI, it shares the Spark app and software functionality. So, you get access to the same 33 amp models, 48 effects, and thousands of presets as with the bigger models. Likewise, the Spark GO also offers the Spark family’s AI-powered Smart Jam and Auto Chord features, alongside in-app video recording and more. It sounds too good to be true, but there is no catch.

That is, unless, you aren’t a fan of integrating your phone entirely. That’s because the Spark GO strips away all but the most essential controls in favour of its small dimensions. You can store four presets to the GO for recall via the preset button when the app isn’t connected (just as with the Spark Mini), and PG has provided a volume control for your guitar signal, volume buttons for your incoming Bluetooth signal and a headphone jack. On the side there’s a power/pairing button, plus a USB C socket for hooking up to a computer as well as charging the internal, rechargeable battery.

The Spark GO represents a ridiculously powerful feature set, with tones to match at a comparative bargain price.

What’s so smart about smart amps?

As well as the tonal options we’ve come to expect from a regular practice amp (multiple amp models, effects and presets), a key component of a ‘smart’ amp is its ability to expand beyond the static features you’d usually get on a traditional practice amp. This is achieved by connectivity, and under-the-hood features for a one-stop practice, jamming and recording solution.

Thanks to mobile and desktop app integration, smart amps can be equipped with a utilitarian hardware control set, with further editing features (additional controls, access to thousands of presets and generally a more friendly, visual presentation) ‘unlocked’ by connecting to a dedicated app. In turn, allowing the app to take some of the strain allows for smaller form factors, and often a reduced hardware cost.

The smart definition continues by providing functions such as Bluetooth audio (for convenient streaming of your favourite songs), and a USB audio interface (for hooking up to a computer for DAW-based recording).

Now, taking the amp away from being a standalone box in the corner of your room and hooking it up to a phone or tablet provides additional possibilities too. That phone you carry around with you is loaded with cutting-edge technology. It can be a camera, an internet connection, and of course, your portal to social media – all of which would never be viable to add to an affordable practice amp. Smart amps exploit this tech with software functionality allowing you to easily use your device to capture your guitar playing – complete with your full guitar tone – and upload it online.
