Positive Grid Spark Go PW

This is a great portable amp. It's incredibly lightweight, it offers a bunch of effects through the app, and it can serve as an interface. With a USB-A to USB-C adapter I was able to connect it to the phone and record music. You can hook it to your guitar strap, and all you need is a short patch cable, 20-30 cm, and you can walk around and play some music. It accepts a bluetooth source, so it can serve as a bluetooth speaker. Finally, it has a 3.5mm output for headphones. It is a great light travel amp which you can take anywhere. I bought it primarily to use with my Traveler silent guitar, and it works great for that purpose.

I'm knocking off one star because I find the speaker underwhelming, even for such a small device. It produces the volume of tone, but the tone is thin. Good headphones fix this issue. The app is a bit buggy. Sometimes it crashes and I have to restart it again. But nothing too dramatic.

All this notwithstanding, I'm absolutely happy with this purchase, and would recommend this little amp if you're looking for something to use when on the road, and also to record some music outdoors.

Overall, a good speaker/audio interface that delivers surprisingly loud sound for its size. It’s perfect for beginners or anyone who just wants to play at home or for friends and family.

I bought it in 2023, and it still works well. However, I did run into one issue: one day, the sound suddenly became much quieter. I discovered that the volume would only return to normal if I pressed on the device physically. I decided to open it, which was quite difficult and inconvenient, and found that one of the solder joints on a chip had come loose, causing one of the legs to detach.

Luckily, my brother was able to help me solder it back, and it’s been working fine ever since. I’m not sure if this issue will happen again, but I assume it might just be a problem with my specific unit or revision.

Overall, it’s a solid product for the price, and despite that one issue, I’m still satisfied with the performance.
