This is the little amp that could, and did, offering 40 watts through a stereo speaker setup, and making its respectable wattage count for a lot. Play it at house-friendly volumes or through headphones, but if the mood takes you, this amp can really sound expansive and loud, with modelling tech that offers valve-like dynamics in a digital practice amp format.

PLAY SOUND

Then you have to consider the idea that the Spark isn’t just an amp. At least, not in the conventional sense.

Spark can analyze a song of your choice from Spotify, Apple Music or YouTube then transpose its chords so you can play along with it

Of course, you have heard it all before with regards to amp integration blah blah, Bluetooth audio streaming yada yada… And sure, the Spark does all that. But the Spark can also analyze a song of your choice from Spotify, Apple Music or YouTube then transpose its chords so you can play along with it. 

Pick a tempo, play a riff or a chord progression, choose the genre you want and it’ll create a backing track for your to jam with. Even the most cynical tone hound would have to raise an eyebrow at that.

The Spark looks like a proper guitar amplifier. It is a table-friendly format, but it isn’t trying to masquerade as a piece of hi-fi equipment to appeal to the home gadget fanatic. It looks good; all that black and gold, and a piping, grill, and control panel that should look reassuring to any player. 

Its portable size and low weight mean you can place it pretty much anywhere in your house and it would not look out of place.

Smart Jam is great but we see Auto Chords as a much bigger deal. This listens to a song of your choosing within the app, and if it doesn’t already have the chords for it on its database, it will analyse the song and transpose the chords for you to play along.

OUR VERDICT

The Spark has all the connectivity, amp modeling and onboard effects you’d expect from a state-of-the-art desktop amp, but it takes the format into the future with its Smart Jam and Auto Chords features. It’s incredible.
