Bluetooth on a guitar amp is genuinely useful for two things: streaming backing tracks to jam along with, and wireless guitar connections that get rid of a cable entirely. The amps below all do at least one of those properly, rather than bolting on Bluetooth as a marketing checkbox.
If you want the full amp buying guide covering every situation, not just wireless convenience, start with our complete guide to travel guitar amps.
One thing we dropped from the old version of this guide: a couple of “Bluetooth amps” that turned out, on checking, to be Bluetooth speakers with no guitar input at all. If an amp doesn’t have a jack for your guitar, it isn’t a guitar amp, however good the speaker is.
Quick comparison
| Amp | Best for | Power | Wireless feature |
|---|---|---|---|
| BOSS Katana-Air EX | Best overall wireless amp | 35W | Wireless guitar transmitter, 12hr |
| BOSS Katana-Air (original) | Best value wireless amp | 30W | Wireless guitar transmitter, 12hr |
| Blackstar Fly 3 Bluetooth | Cheapest Bluetooth amp | 3W | Bluetooth audio streaming |
| Vox ADIO-AIR-GT | Modelling plus Bluetooth | 50W | Bluetooth audio and app control |
| NUX Mighty Lite BT MkII | Cheapest Bluetooth practice amp | 3W | Bluetooth streaming and app editing |
Our verdict: the BOSS Katana-Air EX is the one to buy if wireless matters most to you. The transmitter genuinely frees you from a cable across a room, not just a marketing phrase, and the dual speakers give it a fuller sound than the original Katana-Air. If the price puts you off, the original Katana-Air does almost the same job for less.
BOSS Katana-Air EX
The Katana-Air EX pairs BOSS’s wireless guitar transmitter with dual five-inch speakers in a proper wood cabinet, which is a genuine step up from most “wireless” amps that are really just Bluetooth speakers with a guitar jack. Five amp characters and over 60 onboard effects cover a lot of ground without needing a single pedal.
The transmitter itself runs about 12 hours before needing a charge, plenty for a practice session or a small gig. It’s the priciest amp in this guide, but it’s also the only one that feels genuinely finished rather than a first-generation attempt.
BOSS Katana-Air (original)
Before the EX came along, the original Katana-Air set the standard for wireless guitar amps, and it’s still a genuinely good buy now it sits below the newer model on price. A single 6.5-inch speaker instead of the EX’s dual setup means slightly less low-end fullness, but the same wireless transmitter and five amp characters carry over.
If you want wireless freedom without paying for the EX’s cabinet upgrade, this is the smarter buy of the two.
Blackstar Fly 3 Bluetooth
This is the Bluetooth version of the Fly 3 we recommend elsewhere on this site, and the upgrade is worth it if streaming backing tracks matters to you. USB-C charging gets you up to 18 hours of use, a genuine improvement over AA batteries, and Bluetooth audio streaming lets you jam along to a playlist without any extra cables.
It’s still a 3W amp built for practice rather than performance, but as the cheapest genuinely Bluetooth-capable amp here, it’s an easy recommendation.
Vox ADIO-AIR-GT
At 50W and running on eight AA batteries or mains power, the ADIO-AIR-GT is the most flexible amp here. Eleven built-in amp models cover most guitar tones, and Vox’s Tone Room software unlocks another 23 if you want to dig deeper, all controllable over Bluetooth from your phone.
Stock on Amazon UK is limited for this model at the time of writing, so check availability before making it your first choice if you need one urgently.
NUX Mighty Lite BT MkII
The Mighty Lite BT MkII is the budget pick for anyone who wants Bluetooth without spending Katana-Air money. It streams backing tracks, pairs with NUX’s free Mighty Amp app for tone editing, and includes a built-in drum machine for practising timing, all from a genuinely pocketable amp that runs on six AA batteries or USB power.
It’s a practice tool rather than a performance amp, but at this price, with this much app-driven flexibility, it’s hard to fault. Stock on Amazon UK is limited at the time of writing, so check before you rely on it.
Frequently asked questions
What’s the best Bluetooth guitar amp?
The BOSS Katana-Air EX if you want a genuinely wireless setup with no cable to your guitar at all. If you just want to stream backing tracks rather than go fully wireless, the Blackstar Fly 3 Bluetooth is cheaper and covers that need well.
Does Bluetooth let me play through the amp wirelessly, or just stream music to it?
These are two different features. The BOSS Katana-Air and Katana-Air EX use a dedicated wireless transmitter for your guitar signal itself. The other amps here use Bluetooth only for streaming audio, like backing tracks or a playlist, while your guitar still plugs in with a cable.
Is Bluetooth latency a problem for playing along to backing tracks?
Not noticeably on any of the amps here. Latency matters far more for the wireless guitar signal itself, which is why BOSS uses a dedicated low-latency transmitter rather than standard Bluetooth for that job.
Do I need an app to use these amps?
No, all of them work fine with no app at all. The Vox ADIO-AIR-GT and NUX Mighty Lite BT MkII have companion apps that unlock extra tones and editing, but they’re optional extras, not requirements.
How we assessed these
We checked live UK stock, manufacturer specs and current pricing on Amazon for every amp here, and dropped two amps from the previous version of this guide once we confirmed they were Bluetooth speakers with no guitar input, not guitar amps at all.
