Positive Grid Spark GO 5W Ultra-Portable Smart Guitar Amp, Headphone Amp & Bluetooth Speaker with Smart App for Electric Guitar, Acoustic or Bass

I bought this for my best friend for his Birthday so he can play at work through headphones. First off, the four presets it has stock are great-sounding right out of the box. They chose some very well-crafted tones to show off what the little beast can do.Secondly, it's small, about the size of a disposable camera, maybe a little bigger. But the sound that it can generate is impressive. I turned it up all the way, and had to raise my voice to talk over it. I didn't have to yell; it's not that loud, but it was loud enough. The real magic came through he headphones. I used my Shure Studio Headphones, and the clarity and power coming through was just downright impressive. The sound was articulate, the pick attack was present, and just clear and concise in each preset.Next we tried the App. After some false starts with pairing (user issue, unrelated to the device), we experimented with the available tones before exploring the Tone Library or Jam Session. Unfortunately, the app crashed a few times and seemed laggy, but it has an intuitive interface. I recommend using a tablet for the larger pictures, but a phone works just as well.My assessment is an easy five stars for the little amp, with the caveat that the App is clunky, but easy to navigate. If you play guitar and want to sound like any of your guitar heroes (there are thousands of tones available in the library), get this guy and use the headphones. 5W doesn't seem like much, but straight into your ears, it's more than loud enough, and I'd suggest not doing that (I have bad tinnitus from not listening to people like me now). If you're a guitarist, always protect your hearing.

This is the first piece of gear for my electric guitar to really make me practice more. I was getting too lazy to deal with all my pedals and wires and big amps, so I would just play my acoustic. But this little thing is so fun and sounds so much better than I expected I now prefer my electric guitar. It’s also loud enough to Jam with in an acoustic setting which is surprising based on the size. It even handles Bass much better than I expected.

Only had it for a couple of days but I already know I like it. If you just plug your guitar into it, the little speaker sounds pretty good. Not like a full size amp, it's a little thin, but you can EQ the tone for a little more bottom. When you plug it into a PA system, it really comes alive. You can find any tone you can think of in the Tonecloud and it sounds great! I left my pedal board at home and used it for a band rehearsal last night and it was pretty awesome. The four presets held all my usual tones and once I get the pedal switcher it will be even easier. I plan to gig with it. The tones I've gotten from the cloud are a little bottom heavy, which is why I gave it 4 stars. Like I said before, you can EQ the patches, I just haven't had that much time to play with it yet.After playing with the amp for a couple of weeks and playing a couple of gigs with it, I'm upgrading to 5 stars. I got the Airstep switching pedal to use with it and it made it easy to use on stage. Run through the P.A. the tones you get out of it are as good as you could want in a stage situation. The thousands of tone patches available, the fact that you can Bluetooth backing tracks, the auto chord function, the Jamtracks, and all the other extras in the app make just those things worth the cheap price of this amp. The only drawback is that it's made my pedal board obsolete. I'm glad I got mine before the price goes up, because it probably will with a product of this quality.

Excellent sound and features from a small package. This amp really surprised me! It sounds great for its size with descent enough tone to get into what you're playing. It really sounds bigger than it is. The accompanying app is pretty good and offers a good variety of tweaks to your tone and sound. There is also an AI backing track tool to play with and quite a few conventional backing track styles.I can easily recommend this little amp!

Wow it’s tiny and WOW it does NOT sound tiny. It’s perfect for my beginning-practicing self, so beyond that I can’t elaborate. Super easy to update firmware, which mine required on opening. Mode changes sound great. Overall very pleased and would purchase again.
