1. Positive Grid Spark

The future of home practice

Price: $299/£235 | Wattage: 40W | Effects: 30 Amp Models 40 Effects | Speakers: 2x4" Custom Designed Speakers | Weight: 11.46 lbs/5.2 kg

Excellent value
Easy to use 
Smart Jam/Auto Chords great for practice 
Supply issues can make it difficult to get your hands on one 

Unless you've been living under a rock for the last couple of years, you've heard of the Positive Grid Spark. This innovative smart amp took the guitar world by storm and created demand, the likes of which we've never seen before for a desktop practice amp. 

On the surface, the Spark is a 40-watt practice amp powered by the highly revered BIAS tone engine - but in reality, it's far more than that. When used in conjunction with the Spark app, the amp transforms into the ultimate practice companion. 

Listening to a song and want to jam along? Simply use the 'auto chords' feature to figure out the chords in any song from Spotify, Apple Music, or Youtube. Perhaps you want to jam or write songs? Well, the 'smart jam' feature carefully analyses the notes you're playing and creates a backing track in a style of your choice - how cool is that?! If all of this wasn't enough for you, the app also gives you access to over 10,000 tone presets. 

This clever little amp offers incredible value for money and may just change the future of practice amps forever.

2. Yamaha THR30II

The original desktop amp pioneer

Price: $499/£429 | Wattage: 30W | Effects: 15 Guitar Amp Models, 3 Acoustic Models, 3 Bass Models, 3 Flat Voicings, Chorus, Phaser, Flanger, Tremolo, Reverb, Delay, Compressor, and Noisegate | Speakers: 2x3.5 Full Range | Weight: 9.5 lbs/4.3kg

Simple to use
Fantastic range of sounds 
Built-in wireless receiver  
The look might not be for everyone  

The Yamaha THR series doesn't look much like a guitar amplifier, and that's the idea. Styled after home audio equipment, the THR30II can sit anywhere in the home, and the non-guitarists can stream music to it via Bluetooth.

The guitarists, however, are in for a real treat, because this is a serious desktop amp from the pioneers of desktops amps. With convincing onboard modulation, reverb and delay effects, 15 amp tones courtesy of Yamaha’s Virtual Circuitry Modeling, there is a whole lotta tone here. A pair of  1/4" line outputs make it a great option for home recording.

3. Blackstar ID:CORE BEAM

Bass, Electric, Acoustic, and Music!

Price: $394/£199 | Wattage: 10W | Effects: 6 Electric Voices, 2 Bass Voices, 2 Acoustic Voices, 2 Acoustic Simulator Voices, Modulation, Delay, Reverb and Distortion | Speakers: 2x3” Full Range | Weight: 8.6 lbs/3.9kg

Perfect for bass and acoustic as well as electric guitar
Sounds huge for its size 
Built-in Bluetooth for streaming music 
Not much to complain about 

Blackstar’s BEAM (Bass, Electric, Acoustic and Music) is a popular desktop solution. It’s compact, so it’s great where space is limited, and it features the familiar range of Blackstar clean and overdrive sounds, together with studio-quality modulation, delay and reverb effects.

You can stream music via Bluetooth, although you’ll need a USB cable to get into deep editing with Blackstar’s Insider software. What the BEAM lacks in features and models it more than makes up for by being simple, fun and great value for money to boot.

4. Boss Katana-Air

The cutting-edge wireless desktop amp

Price: $412/£369 | Wattage: 30W | Effects: 5 amp voices and over 50 effects | Speakers: 2x3” | Weight: 4.14lbs/2.2kg

Iconic Boss effects
Fully wireless  
A little expensive compared to the standard Katana  

The Katana amps have been a big success story, with Roland adding its digital might to make them a popular choice for guitarists wanting to jump to digital. The Katana-Air’s boast is that it was the first fully wireless amp of its type, bundled with a Boss guitar transmitter.

There are just five amp models, but they’re truly awesome and you can access over 50 Boss effects. Audio streaming and editing via Bluetooth is standard, and the Katana can run on batteries. Power output is a respectable 30 watts (2x 15 watts) when plugged into the mains adaptor.

6. Laney Lionheart Mini

A small amp with a mighty roar

Price: $99.99/£39 | Wattage: 3W | Effects: Clean/ Overdrive (Lots more when using TONEBRIDGE app) | Speakers: 1x3" | Weight: 1.65 lbs/0.75 kg

Tiny size
More features than other mini amps  
Needs subscription to Tonebridge app to fully unlock amps potential 

The market is awash with mini versions of famous amps. Although the Laney may not be the most recognizable, it may be the best. This petite 3-watt amp delivers a big sound that is more than enough for at-home practice, and the rather attractive navy exterior and blue and beige grill cloth means it looks great as well. 

What sets this amp apart from the competition is the Laney Smart Interface socket (LSI). This nifty addition allows you to connect the amp to your smart device and use third-party apps to access new and wonderful sounds. Laney recommends using your new amp with the Tonebridge app, and all Laney mini amps come with a free 3-month full subscription to get you started.

7. Vox Adio Air GT

Classic Vox styles with modern technology

Price: $299/£249 | Wattage: 50W | Effects: 11 amp voices (23 with app), 8 effects (19 with app) | Speakers: 2x3” | Weight: 6.39lbs/2.9kg

Looks great
Great sounds  
Other amps in this category have more features 

This is a strong player in the desktop amp field, helped by Vox’s partnership with another giant in the digital music field, Korg. It has a powerful 50-watt (2x 25-watt) power output, 17 amp models and up to 19 effects. The Adio can do audio streaming and remote editing via Bluetooth using Vox’s Tone Room app, and it can run on alkaline or rechargeable batteries.

The Adio is also bundled with the popular Jamvox app. There’s no guitar wireless, but you can buy one of several popular transmitter/receiver kits to use with the Adio Air.

Best desktop amps: Blackstar Fly

8. Blackstar Fly

Practice your guitar on the fly

Price: $69.99/£49 | Wattage: 3W | Effects: Clean/Overdrive and Delay | Speakers: 1x3” | Weight: 1.9lbs/0.9kg

Extremely light-weight 
 Affordable  
A little basic  

As far as portable, battery-powered practice amps go, the Blackstar Fly may be the most popular one out there. This tiny 3W amp not only delivers two channels (clean/ overdrive) but also ‘tape delay’. 

Blackstar offers a Fly Stereo pack (or separate FLY 103 extension cab) which turns this mighty little amp into a 6W stereo rig. This sounds great for guitar but even better for music playback or even PC monitors. 

The Fly is portable, loud, and best of all extremely affordable! 

Marshall CODE25

9. Marshall CODE25

Every Marshall tone imaginable in one small unit

Price: $269/£149 | Wattage: 25W | Effects: 100 preset, 24 different built-in effects (5 simultaneously) | Speakers: 1x10” | Weight: 13lbs/6.1kg

Classic Marshall look
Great sounds  
Other amps at the same price point may have more features 

Not quite a desktop amp but still a potent rival, Marshall’s CODE25 has a cracking remote editing app that really makes the amp come alive. Again, the CODE streams audio via Bluetooth making it a great play-along tool. No stereo here, but a beefy 10-inch loudspeaker makes it more of a ‘proper’ guitar amp, capable of handling the odd small gig with ease.

There are 14 preamp models, four power amps and eight cabs, with 24 effects – you can use up to five simultaneously. Best news is the price: at $340 MSRP, and available at heavy discounts across the web, the CODE25 is amazing value.

Sound 

It may sound obvious, but the most important thing to think about when choosing the right desktop amp is the sound. Unfortunately, not every setting on these multi-channel amps is of equal quality. 

Think about the tone you will use 90% of the time and find an amp that can reproduce that. If you're a blues player, you may want to look for an amp with an authentic low gain sound and a nice spring reverb. For us, the Yamaha THR30II does a great job at achieving this sound. If metal is your thing, then make sure the amp you choose has a solid high-gain setting. The Blackstar BEAM, Katana-Air, and Positive Grid Spark handle the high-gain sounds very well in our opinion. 

Effects 

Next, we need to consider effects. Each amp on this list comes with access to multiple guitar effects, from delay to reverb, compression to chorus, and many more. Playing around with effects can get a little confusing - especially for beginners. The Fender Mustang LT25 has a very simplified layout and is very beginner-friendly. If you find yourself wanting to experiment with effects, then look at the amplifiers with integrated apps, as usually, this means you can download extra effects and presets whenever you want to try out new sounds.  

Wattage 

Each amp on this list has more than enough power for home practice, although this can vary significantly. Most mini battery-powered amps come in at 3W, and the larger options go up to 40W. So make sure you consider the wattage carefully.
