Review: It's NOT a toy - 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!
Review: Amazing. - 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.
