Positive GridSpark 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.

Exactly what I wanted for casual playing. I love positive grid computer software but I didn’t like to turn on my computer and login into their platform to start to play so this device just meet my needs.The device building feels high quality.The steps to use it as BT audio output when it’s already connected to the smartphone app can be tricky but it will be fine if you follow the manualI haven’t tried all the effects I usually use from the tone cloud but so far it seems everything just works

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.

I have the Spark 40 and this little guy, love them both. lots of uses. Practice capacity:travels etc

Just to flex my street cred (kidding), I've played guitar for 25 years and have several amps ranging from tubed half stacks to smaller, lo-watt combos, to a couple other battery powered amps because they're fun to play even after the neighbors go to bed. This is my first experience with a Positive Grid product and so far the impressions are good.I purchased the Spark Go to dip my toe into the world of Spark. The price is really good for what you get. At it's core, the device itself is essentially a bluetooth speaker with a quarter-inch input and 4 memory banks for configurations saved in the app.The app is where the real power is. It's fun to play around with the pedal settings and dial in a sound worthy of the 4 memory slots. I'm still trying to decide. You could theoretically use this without the app, but half the fun is configuring the sounds that make you want to practice and ultimately not have to use the app so much once it's all set up. The UX of the app is pretty okay. Lots of skeuomorphic elements that fans of GarageBand will find familiar.The sound is decent, especially for drives, modulation and delays. Reverb is laughable and barely audible through this speaker. It feels solid and a lovely little piece of kit.I wish there was a drummer built in, but bluetooth makes it easy to stream drumming backing tracks. Time will tell how this amp works down the road. Who knows if they stop supporting the app / device down the road and we all have fancy door-stops. But hopefully this is something... disruptive to an industry that will not be disrupted.The Spark makes it easy to get going and makes practicing more accessible. I'm still messing with the settings more than I'm playing the guitar, but i'll find my stride soon-enough. I would recommend buying this for any guitarist that's half-way tech savvy.
