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

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

Exceeded expectations - brilliant for practice.Had a few of the bigger Spark Amps over the years then moved onto modellers now I’m back in the fold with this great little amp; all the features I need and plenty loud enough for my bedroom noodling. If you’ve never tried Spark amps and software before - this is an economical way in and something you’ll want to keep.Sound quality is excellent and it’s brilliantly made and packaged - hats off to Positive Grid.

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!

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.

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.

I already owned the excellent Spark 2 but was very impressed by the portability of the tiny Spark Go. Used in conjunction with the Spark App this is a brilliant little amplifier, using the built in speaker or headphones it sounds great. A wonderful way to practice, with it’s internal rechargeable battery you can use it anywhere.

Lovely piece of kit. I wanted something small which I could use without lugging my amp out and annoying the people downstairs. This fits the bill perfectly and more. There are recording features which I've not tried yet but sadly the recording software they used to give out free is no more.All in all this is great and if you plug headphones in the quality of sound is even better. Worth every penny.It's worth noting though that this amp only has 4 presets without the app. The app is key to using this device so if that puts you off you probably need to look at some other alternatives out there.

Brilliant piece of kit, sounds amazing and works great as a Bluetooth speaker
