No. 1 · EDIT'S PICK
Boss Katana Mini X
around £138 (price checked 14 Nov 2026)
A 10-watt portable combo with a 5-inch speaker, three amp types (Clean, Crunch and Brown) each with a variation, built-in effects including reverb and delay, a tuner, a headphone socket and Bluetooth audio for playing along to music. It runs on a rechargeable battery charged over USB-C.
Why we picked it
Guitar World calls it the mini amp to buy right now and names it the best tactile pick in its mini amps guide, singling out how loud it goes and how good the headphone output sounds. Everything is set from the front panel, so there's no app to wrestle with. The reviewer's complaints are that the delay time is fixed, there's no USB recording, and it can't be played from the mains.
Best for: Players who want a small, battery-powered amp with real knobs and no app to learn
Skip it if: You want to record into a computer over USB, or need it to run from the mains.
| Power | 10 watts |
|---|---|
| Speaker | One 5-inch |
| Battery | Rechargeable, up to about 10 hours |
| Headphone out | Yes, 3.5 mm |
| Bluetooth | Audio streaming |
| App | None needed |

No. 2 · BEST VALUE
Blackstar Fly 3
around £59 (price checked 14 Nov 2026)
A 3-watt mini amp with a 3-inch speaker, clean and overdrive channels, a tape-style delay, an aux input for playing along, and a headphone output with speaker emulation. It runs on six AA batteries or an optional mains adapter.
Why we picked it
Guitar World names it the best budget mini amp and calls it brilliant value for practice, and MusicRadar says it should be near the top of the list for a portable practice amp, praising the drive channel and the delay. Both point out the plastic build, and Guitar World notes that neither batteries nor a power supply come in the box, so budget for one or the other.
Best for: Beginners and anyone who wants a cheap, simple amp for the bedroom or a desk
Skip it if: You want lots of sounds, Bluetooth, or an amp that comes ready to plug in.
| Power | 3 watts |
|---|---|
| Speaker | One 3-inch |
| Channels | Clean and overdrive, plus delay |
| Power source | Six AA batteries or optional adapter |
| Headphone out | Yes, with speaker emulation |
| Bluetooth | No |
Retailer links coming soon.
No. 3 · NEW ARRIVAL
Blackstar Beam Mini
around £148 (price checked 14 Nov 2026)
A 2026 desktop modelling amp with two 2-inch drivers and passive bass radiators, 12 amp models, a large library of downloadable amp captures, effects, five onboard presets, Bluetooth audio, a headphone output and USB recording. MusicRadar and Thomann list up to 18 hours from the built-in battery.
Why we picked it
Guitar World ranks it the best mini amp overall, and its reviewer calls it their favourite mini practice amp, praising the realistic amp models and the bass response. MusicRadar gives it five stars, adding the long battery life and app learning tools to the list. Both say deeper editing needs the app, and Guitar World found the side-mounted input awkward on a busy desk.
Best for: Players who want the most realistic amp sounds in a desk-sized box, plus a strong Bluetooth speaker
Skip it if: You'd rather not use a phone app to fine-tune your sound.
| Power | 2 x 12 watts |
|---|---|
| Speakers | Two 2-inch, with passive radiators |
| Battery | Up to 18 hours |
| Headphone out | Yes, 3.5 mm |
| Bluetooth | Audio streaming and app control |
| Recording | USB |

No. 4
Positive Grid Spark Mini
around £149 (price checked 14 Nov 2026)
A 10-watt battery-powered smart amp with two 2-inch speakers and a passive radiator, 33 amp models and 43 effects in the Spark app, a headphone output, Bluetooth audio, and app features such as Smart Jam, which builds a backing track from what you play.
Why we picked it
Guitar World names it the best mini amp for metal, praising the high-gain sounds, the volume for its size and the companion app. MusicRadar calls it a fantastic-sounding mini modelling amp and found the battery claim of up to eight hours realistic below half volume. The catch, in both reviews, is that you need a phone for full control, as the amp itself has few knobs.
Best for: Rock and metal players, and anyone who likes practising along to backing tracks from an app
Skip it if: You want to change sounds without picking up your phone.
| Power | 10 watts |
|---|---|
| Speakers | Two 2-inch, with passive radiator |
| Models | 33 amps, 43 effects (via app) |
| Battery | Up to 8 hours |
| Headphone out | Yes, 3.5 mm |
| Bluetooth | Audio streaming and app control |
Retailer links coming soon.
No. 5
Positive Grid Spark GO
around £88 (price checked 14 Nov 2026)
A pocket-sized 5-watt smart amp with a single 2-inch speaker, the same Spark app with 33 amp models and 43 effects, a headphone output, Bluetooth audio and a rechargeable battery rated for up to eight hours.
Why we picked it
Guitar World names it the best compact mini amp, calling it louder than you'd expect and praising the range of sounds. It notes that bass can get flabby with low tunings, and that the input placement means a cable can pull the little amp over.
Best for: Players short on space, or who want an amp that fits in a bag for travel
Skip it if: You play in low tunings, or want controls on the amp itself rather than in an app.
| Power | 5 watts |
|---|---|
| Speaker | One 2-inch |
| Models | 33 amps, 43 effects (via app) |
| Battery | Up to 8 hours |
| Headphone out | Yes, 3.5 mm |
| Bluetooth | Audio streaming and app control |
Retailer links coming soon.
No. 6
Fender Mustang Micro Plus
around £120 (price checked 14 Nov 2026)
A headphone amp that plugs straight into your guitar, with 25 amp models, 25 effects, 100 preset slots, a small display with a tuner, Bluetooth audio, USB recording, and the Fender Tone app for editing. UK retailers list battery life at over four hours.
Why we picked it
Guitar World names it the best headphone amp for guitar and calls it a brilliant option for practising, praising the clean sounds, the reverbs and how simple it is to use. Its reviewer found there's no quick way to jump between presets, and that bass-heavy sounds can overload at high volume.
Best for: Silent practice in flats, late at night, or anywhere a speaker would disturb someone
Skip it if: You want to play out loud, or switch sounds quickly mid-song.
| Type | Headphone amp (no speaker) |
|---|---|
| Models | 25 amps, 25 effects |
| Presets | 100 |
| Battery | Over 4 hours |
| Bluetooth | Audio streaming |
| Recording | USB |
Retailer links coming soon.
No. 7 · BEST PREMIUM
Boss Katana 50 Gen 3
around £255 (price checked 14 Nov 2026)
A 50-watt modelling combo with a 12-inch speaker, six amp voices each with a variation, Boss effects, a headphone output and a power control that drops it to 25 or 0.5 watts for quiet playing. Editing goes deeper in the free Boss Tone Studio software.
Why we picked it
Guitar Player names it the best practice amp overall, praising the amp sounds, the Boss effects and the value. MusicRadar calls it a great-sounding, feature-laden amp and liked the new Pushed voice. Both flag that Bluetooth needs an optional adapter, which MusicRadar puts at about £45, and at 11.6 kg it's far bigger than the rest of this list.
Best for: Players who want one amp for home practice that can also handle a band rehearsal
Skip it if: You're short on space, need it to be portable, or want Bluetooth built in.
| Power | 50 watts, switchable to 25 or 0.5 watts |
|---|---|
| Speaker | One 12-inch |
| Weight | 11.6 kg |
| Headphone out | Yes, 6.3 mm |
| Bluetooth | Optional adapter |
| Power source | Mains only |

How we chose
We started with the practice amp and mini amp guides from Guitar Player and Guitar World, Guitar World’s headphone amp guide, and individual reviews from Guitar World and MusicRadar. That gave us a shortlist of around a dozen amps, which we cut to ones on sale new in the UK now for under about £300.
For playing at home, we weighed how good an amp sounds at low volume and through headphones most heavily. A practice amp that only sounds right when it’s loud is the wrong amp for a flat. Ease of use came next, then extras such as Bluetooth for playing along, battery power and app control.
We also wanted a spread of needs: an all-rounder most people can buy without regret, a cheap option, a new arrival with the most realistic amp sounds, app-driven smart amps, a headphone amp for silent practice, and a bigger amp that can also cope with a rehearsal.
This guide is based on manufacturer specs, retailer listings and expert reviews, listed below. We haven’t played these amps ourselves. Prices are typical UK prices on the date shown beside each pick, and they move around Black Friday and Christmas.

FAQs
How many watts do I need for playing at home?
Not many. Guitar Player suggests 10 to 20 watts is the sweet spot for home use, and that bigger amps should have a way to turn the power down. Mini amps of 3 to 10 watts, like the Blackstar Fly 3 or the Boss Katana Mini X, are plenty for a bedroom.
Do I need a headphone output?
Guitar Player recommends one even if you don't think you'll use it straight away. Every amp in this guide has one, and the Fender Mustang Micro Plus works only through headphones.
Is Bluetooth worth having on a practice amp?
It lets you stream songs or lessons from your phone and play along through the amp's speaker. Guitar Player notes that some players still prefer a wired aux input because Bluetooth can add a slight delay. The Fly 3 has an aux input instead, and the Katana 50 Gen 3 needs an optional adapter.
Do I need the app to use a smart amp?
On the Positive Grid Spark amps, mostly yes, as both Guitar World and MusicRadar point out the amp itself has few controls. The Blackstar Beam Mini works from its top panel but needs the app for deeper editing. The Boss Katana Mini X and Blackstar Fly 3 need no app at all.
