BOSS Ktn-Mini Katana Portable Guitar Amplifier, A Compact, Go-Anywhere Amp That Runs On Batteries - Rich, Full Sound

This thing is incredible. Very good sound, good battery life and with the accompanying app has a massive range of uses. Very happy with the purchase and would recommend to anyone.

What a fantastic practice amp. I have it’s 50watt bigger brother and in comparison where quality of build and sound is concerned they are on a par. Obviously this doesn’t have massive amounts of effects on board, but it gives lovely clean tones, great dirty tones and excellent delay, there is a switch to select clean, crunch or brown, you then alter the settings using the volume, gain, bass, middle, treble, time and level controls. All of the settings are excellent and no matter what your preferred tone is, you will find it on this amp. There is an audio input to attach a microphone or allowing you to play a jam track, drum app track or favourite song to play along with from a phone or mp3 player, this input is totally unaffected by any of the controls on the amp, even the volume which is altered using the phone/mp3 players own controls. There is an output for headphones or recording device i.e. pc, laptop, voice recorder. It is light and compact and can be carried anywhere when used on batteries, 6x AA batteries required. I haven’t changed mine yet since purchasing this amp and it’s used daily.

Dropping a star for complexity, but it does deliver on the features. To configure this, you'll need an App, and one day, Roland will pull it from Google Play and the Apple Store when this is considered obsolete. I personally wasn't that interested in all the "pedal" effects, but did want the Bluetooth audio playback capability, and USB recording. This is a good alternative to the Mustang Micro Plus, though arguably better for a Bass, as it has a bass-specific mode. Bluetooth Pairing is not trivial, as you effectively do it twice: once for the configuring App (Bluetooth MIDI) and once for audio streaming (Bluetooth Audio). However, it gives you the flexibility to configure using one device and stream your backing track from another. Playback can be done over USB-C - note for iPads, the audio playback level seems to be fixed (unlikely playback via Bluetooth). Easily adjusted on the Katana Go itself, but annoying as that affects both the Guitar and backing track volume. App is a little clunky (as seems to be common for the Boss apps) - fixed portrait mode, and scaled up (pixelated) on large displays such as an iPad. However, it is only needed for configuring. The "stage feel" button is great. This works for both the guitar and the backing track streamed over Bluetooth (different from the reverb effect on the Mustang Micro, which only affects the guitar). Tuner works for a "low B" on a five (or six-string) Bass. A minor disagreement with my Peterson Strobestomp tuner on that low B, but near enough given that string is hard to tune accurately. Yet to find a clean-clean Bass setting (one without compression - a.k.a. Studio mode on the Mustang Micro). This can be achieved in the app, but it would have been nice as an easily accessible default. During solo practice sessions, you want to hear all your faults.

Having previously used/suffered a succession of 'toy' amps (Orange crush, mini Marshall stack, etc..) I'd been after a 'sofa amp' for ages. You know- when you want to noodle away when watching TV but don't want to bring anything bulky downstairs... So I'd decided on the Blackstar Fly or this. SO happy I chose this! Nothing wrong with the Blackstar Fly- it's a cracking little box. But the Katana mini is awesome! Once you get it dialled in properly (keep the treble below halfway) you'd swear you had a 'real' amp sitting there by the fireplace. All three channels are perfectly useable. The gain knob works very well with each, and combined with your guitars volume knob you can tailor pretty much any tone. Delay is a nice feature too, with time and level controls. (TIP - turn the time all the way down and the level up to get a half decent reverb!) Crunchy gain sounds are rewarding, as is the high gain 'Brown Sound' setting. If, like me, you are convinced your family/spouse/pets need to hear your version of that-bit-you-can-play-from-Eruption, then you have found your practice amp!

Amazing kit. Makes me sound better than I am. Need to learn to use even 10% of what it can do.

Great sound for such a small unit. Worth the price in my opinion.

Wow what a cracking little Amp the Boss KTN mini is. The output of sound belise the size of the little 7 watt amp. My 20 watt cube and 15 watt mini cube are Roland's, and a bit heavy to shift about. This lives up to the Roland name with knobs on. Works great with my Epiphone Sg 400 and Guild Acoustic along with my Taylor acoustic guitar. Really nice Amp. Decent price tag quality product despite being plastic a really good build quality. No problems in recommending this Five stars.👍🎛️

Sounds great, loads of effects to play with, bought it for my guitars, but found out it also can be used with a Bass guitar, so have ordered a bass to go with it
