Overall Rating 4.9/5 (46 reviews)

Absolutely brilliant for home use. I could play straight away, and within a couple of minutes I could get the sounds I wanted. A bit more tweaking and exploring is needed to get the most out of its features, but if I can do it anyone can. Only briefly tried out recording, but I’m really only interested in practicing. Pros: great range of sounds, through choice of amps and pedals; the jam feature is great, along with backing tracks from YouTube; it sounds great at low volumes, but can go LOUD!! Cons: it is too ‘bassy’ to use as a Bluetooth speaker for music, however I’ve been able to save settings that I’m happy with for the guitar; a looper would have been perfect considering the main intended use of the amp; I like the idea of the additional foot pedal controller, but I’m not paying c50% of the cost of the amp for it. Overall, if you want something small for home practice that sounds great and is good fun, just get it!

The Spark Positive Grid is a great practice amp which is packed full of features. Currently the best practice amp on the market.

ALEX M. - 9/2/2023

Had been thinking of changing electric guitar as not happy with it. My teacher suggested a new amp. From a bit of research this one sounded good - and it amazing! Transformed the sound of my guitar and I just love playing it now - have only scratched the surface of its capabilities. Great value for money too. And it works with my acoustic!

Brian C. - 19/1/2023

Bought spark40 amp and crybaby, amazing set of tones on amp alone, but the crybaby definitely work’s excellently with amp. Also the tones on cloud that you download on app are absolutely brilliant.

Great product easy o set up with the app

THOMAS G. - 14/12/2022

Awesome product,delivered with efficient responces

John H. - 13/10/2022

Bought on the basis of all the positive hard-copy and online reviews. I can't fault the seller's service and so far I'm very pleased with the amp itself. It would have been nice to use the Spark app on my PC but it seems that it only works properly on Android and iPhone devices. Perhaps Positive Grid will have something for Windows in the future. Anyway, try and buy. :^)

Michael H. - 29/6/2022

Dennis B. - 28/6/2022

Mostly very good. Sound is bass heavy regardless of sound source. Sometimes clarity is vague but for what it is I’ve no complaints. It isn’t a valve amp. Could do with a software update to lessen the bass throughout .

Leslie L. - 23/6/2022

Cracking practise amp. Plenty of setting to get the sound you want. Maybe a bigger toggle switch would suit us banana finger players better.

Edmund T. - 17/6/2022

I've had few practice Amps over the years including the boss katana mk2 which is good its just a bit more of mission to access guitar patches and all effects pedals through a connected laptop or PC where as the spark is lot more convenient with a app on phone and alot more portable and the big plus being Bluetooth I can only say I think positive grid have obsolutly nailed it thumbs up ?? ??

Ian P. - 28/2/2022

Excellent product. Great sound and once linked to the app it opens a whole range of tonal options. Easy to operate and have already updated sound cloud twice.

ST-Elmo B. - 14/2/2022

It is exactly what I needed to get me playing guitar again. The wealth of tones you can achieve is incredible and all these tones along with the app features (e.g. backing tracks) can inspire you to play a lot. A perfect practice amp. People have been complaining it's too bass-heavy. Maybe...? I don't know. If you don't compare it side by side with another one you can't tell the difference. If you are an audiophile and are looking for perfection, you wouldn't get a budget all-in-one amp anyway. If you just want to play a ton of things and get 90% of the way there in terms of tone, get this one. I highly highly highly recommend it.

Faidon L. - 13/2/2022

This amp is so loud for something so small and the features are just excellent. Syncs easily to my iPhone via the app & is easy but to use. The build quality & and styling are excellent & it is feature in the front room just like my B&W Zeppelin, that is how good this amp looks.

Philip H. - 13/2/2022

Brilliant box of tricks. Helping me to improve my mediocre playing. So many features to try out and a lovely sound. I love it.

Derek B. - 8/2/2022

See above for my views. Oh and it was delivered promptly.

Raynor N. - 13/11/2021

So much to try out...but up to now all is great. Only one criticism, its got to much bass, so I'm using it with the bass on minimum
