Positive GridSpark GO 5W Ultra-Portable Smart Guitar Amp, Headphone Amp & Bluetooth Speaker for Electric Guitar, integration with the Spark app

It’s tiny, you immediately think it’s going to be no more than a toy. Feels solid, comes with two grills, two handles but still it’s tiny. Plug it in and prepare to be absolutely gob smacked at the sound coming out of this thing, check to make sure you didn’t plug into a large amp, nope this little thing sounds absolutely amazing. I’m stunned at the crisp clear sounds emanating from something so small it impossible but true. Pair the app and prepare to pick your jaw off the floor, it’s thousands of amps in one, metal, rock, blues, pop, acoustic this little thing handles them all delivering clear tone and killer volume. It’s versatile, you can plug it into a powered speaker, it’s simply stunning. Paired with wireless transmitter and people will struggle to understand where the sound is coming from it’s a complete game changer. My Roland Cube is redundant this is my favourite purchase of the year. It’s also a Bluetooth speaker, plays jam tracks, guitar amp and it fits in your pocket !!! Absolutely the best practice amp. Battery life is epic. For the price this thing punches way above in terms of quality, sound and functionality. Simply stunning !!

Huge sound for such a tiny unit - doesn’t lose the tone at lower volumes and is so simple to use. Most other practice amps have sounded tinny and rattling but this offers warmth and rich sounds, with a wealth of effects and amp models thrown in for free- versatility is an under statement when it comes to this amp!Choice of grills, both of which are well made give it a nice appearance, unbeatable on portability, performance and size.I’m a skeptic when it comes to practice amps; but this one is deceptively good. Great value for money and perfect for when you just want to plug and play without the hassle

Wonderful little amp that, despite it's size, packs a really good sound. The download able tones are a great feature and everything can be tweaked to your satisfaction. Works really well with the Spark app.

Owning a GO is the cheapest way to gain access to the incredible Spark App and its huge sound library. Whilst the speaker on the GO is fine for a quick practice, plug it into a larger amp to get a full, rich and huge sound. Best guitar product I’ve bought in ages.

It's very small but the sound is very big and it is a breeze to use.There are limitations- you have no control over the 4 presets unless connected via Bluetooth to the Spark App on a tablet or mobile phone. I connected to both with no trouble at all and the app gives easy access to a huge range of presets, control over individual presets and many other services online.The quality of individual patches is excellent and distorted amp patches respond well to backing off guitar volume and tone controls.The internal power amp is pretty loud and for practice you wouldn't need anything else.For ultimate sound quality a set of quality over-ear headphones or a stereo power amp set up is a must.I have just been running mine into a power amp through separate modulation and reverb/delay units and the result was awesome. It would be fiddly, and you would need a good monitoring set up, but you could gig with this.I can't comment on battery life, it lasted 2 hours with plenty to spare and you could carry a power bank around if that was a concern.The hanging loop supplied wasn't much use to me as I use wide straps with strap locks and I figured it would be a pain to get on and off, so I drilled out a small right-angled bracket to suit and attached that with a carabiner and some strong velcro loops so it can be moved easily between guitars or taken off for charging. If you are going to hang it off your strap it is worth investing in a short (30 cm or so) guitar cable. I made one up with right angled jacks, one of the silent variety so no nasty noises if I disconnect without turning it off!

This is an awesome bit of kit for someone who wants get a bit of amplified practice in anywhere without all the bother of getting your amp etc out. It fits in your guitar case and only requires one short lead and is rechargeable so no power source required either. It is loud enough to easily join in on your electric guitar with people on acoustics or piano.There are four pre-sets ranging from a nice clean sound progressing up to a surprisingly decent crunchy metal sound with good reverb etc. There is also an app that links to the spark where you can adjust these sounds or model your own, personally I think the presets are fine as they are. The app also has a myriad of backing tracks, tutorials etc etc.It is also a really good Bluetooth speaker. Not only that but you can play your guitar at the same time as a tune from your phone so it really sounds as if you are the extra member of your favourite band! There are separate volume controls for the Bluetooth and the guitar so you can get the balance how you want it.For a hundred odd quid I really can’t fault this. If only these were about 40 years ago when I started out.

Unbelievable sound output with a very easy to use APP that opens a whole world of effects and amp types.

Great little piece of kit - it sounds fairly loud even outdoors. I often use it as a Bluetooth speaker for my phone. Playing along with backing tracks from your phone is also great. 10/10
