If you are looking for a small guitar amp, Blackstar Fly Mini Amp this may be the right choice for you. Only 3W (without the extension unit) but you can still hear the roar.
Also, you've always seen it on my desk during my videos so, it's time to talk about it. Feel free to ask me any questions, if you have any. Here some specs:
3 Watts producing true Blackstar tones
2 Channels – Clean and Overdrive
Digital ‘tape’ delay effect
MP3 / Line In for jamming along or listening to music
Battery or DC powered
