Description

A tiny battery amp for practicing anywhere or silently through headphones. Tones come from the same Spark app as the Spark 40, and it doubles as a Bluetooth speaker.

The Spark GO was a small investment, it isn't expensive. Different from the other Spark that's a bit bigger, the Spark MINI, this one is really tiny. It fits in your pocket and it's genuinely made to be taken anywhere, you can even clip it to your belt with the strap and walk around with it. It has a tuner and four hardware memories.

Impressions

Its problem is also its big advantage, because it's very small. It has all the features of the Spark 40 and of any other Spark, so you can use the same app for any of them, which is absurdly fantastic, because you basically have a billion amplifiers inside your own amplifier. And it's minuscule, so you can just play anywhere. Even being that small it gets very loud, and the design is very beautiful.

What it doesn't have is the knobs of the Spark 40 or the other Sparks, so it's a bit annoying to play with, because you need the app the whole time. Unless you've saved the tone into one of its memories, you'll always need the app, otherwise you can't play.

The thing that irritates me is the same thing that's the best about it, the size. When you stand it up, the guitar cable goes in through the top of the Spark instead of the back or the sides. With a right angled cable that's fine, it doesn't put much pressure backwards or sideways, so it stays solid. With a straight cable it pulls the weight to one side and you have to play with it lying down. I think that's actually a design decision, because the back of it is rubber, so I think it's meant to be laid down and played that way.

There are some smaller problems that come from it being so tiny. My wireless receiver has a washer at the base of the jack, and when I play, mostly bass, the amp vibrates a lot and that washer vibrates along with it and starts making noise. So there's a specific angle I have to leave the receiver at to avoid that vibration sound while I'm playing, which is very strange and very bad. Some cables don't fit it either, because the jack sits a bit inset into the top and they end up fouling the volume knob.

The battery lasts a good while. I don't know if that's because I play little, but I only have to charge it once a week, sometimes once every two weeks. In one continuous session it doesn't last that long, I'd say three or four hours at most playing constantly, which is a good benchmark anyway.
