Solidly built little amp ideal for home practice. The accompanying app works well. A bit light on bass but that's expected at that small size. Clean tones are excellent.

Mr T Cogan26th Sep 2023

It's a good looking unit and I thought a better sound than the Go in a side by side comparison but the Go is a bit smaller. The app is amazing as so many combinations of amps and pedals to try. Also plugged in my ipod and sound from that is great too. A good mobile speaker and when guitar is plugged in, you can jam along too. Very impressed. I'm using it for a homemade 3 string cigar box guitar but now looking at getting my first proper electric 6 string. Back to Andertons I guess?!!

Great sounding battery amp. A bit disappointed effects like chorus need to be paid more for.
