40W Smart Amp with Tone Presets and Practice Features

Positive Grid's Spark is a breakthrough new way to jam, track, practice, and learn songs. This powerful app-driven smart amp delivers a bedroom-filling 40 watts of 10,000+ classic BIAS amp/pedal/cab presets through its twin 4-inch ported hi-fi speakers, ready for direct injection into your DAW recording session or live PA via USB or 1/8-inch TRS headphone output. And impressive as that is, it's just scratching the surface of all that Spark can do for you. Voice control via the Spark App gives you Slash-worthy lead tones and solo-ready rock and blues backing tracks without lifting a finger. You can even feed Spark your own chord progressions and listen in amazement as a virtual session drummer and bassist accompany you in real time. A massive list of downloadable tone presets and an impressive library of virtual pedals and amps — which are easily navigable by style, artist, or genre — suit this one amp for every electric guitar, acoustic, and bass in your arsenal. And at a mere 11.5 pounds (slightly less than a bowling ball, slightly more than a gallon of paint), the Positive Grid Spark is transportable enough for day-to-day outings.

Delivers 40 watts through twin 4-inch speakers

Though it won't fill an arena, the Positive Grid Spark easily packs enough power for practices and jams around the house. Its stereo 4-inch hi-speakers are deceptively full sounding. So whether you're playing clean funk bass or drop-tuned metal guitar, you get a nice, round low end and great definition right out of the box. Of course, you've also got an auxiliary output and USB port for more direct modes of amplification. We at Sweetwater have found the stereo speakers even hold up favorably to close-miking, so even in a traditional club with a couple of mics onstage, Spark is the only tool you're going to need.

Loaded with over 10,000 presets

One of the Spark's most appealing features has to be its tone presets. In our tests, it was ultra-quick to dial just about any tone we were feeling, from compressed country cleans to fire-breathing metal gains. App-based browsing and voice control make it relatively easy to dial in the tone you're searching for — speaking commands like "Plexi," "Kerry King," or "blues" into your paired mobile device gets you a curated selection of tones to choose from — and in our experience, they provide a great launching point.

A breakthrough way to practice, track, and learn music

A powerful playback system and a vast library of sounds is just half of what sets the Positive Grid Spark apart. Through the app, you'll find countless ways to round out your music-making journey.

  • Live backing tracks: Crank out a chord progression, and the Spark app will automatically accompany you with a bass guitar and drums. You don't even need to set a key or tempo — just strum and go.
  • Multitrack recording: Got a riff you want to preserve or flesh out for further working? Connect the Spark amp to a computer via USB and you're all set to layer guitar and bass tracks by the dozen if you so desire.
  • Chord recognition: Import songs from your Apple Music library, YouTube, or Spotify, and the Spark app feeds you a chord chart on the fly. It's the ultimate fakebook!
  • Riff training: Having trouble tracking that "Spanish Fly" intro run at concert tempo? The Spark app lets you slow down songs and take them at your pace until you can work up to full speed.

Awesome!

An awesome amp,with the app it is a game changer as it for me anyway gives practice a element of added fun playing with a sound track it gives a band feel. Helping with the rhythm and tempo. Not to mention all the different amp and effects combos. Plus it can be ran through a speaker cab. Awesome!

Most Exciting Innovation To Modern Amplifiers

To start with, I'm not one for reviews. However, with the utmost sincerity I had to write a review many people like me needed to read. I have had my share of amplifiers over the years; Solid State, Tube, Hybrid, and have loved the versatility of tones I have accumulated over the years. I've even owned a Positive Grid Guitar and Bass Rack Amplifier. Unfortunately, due to the cost of living in my area rapidly outpacing wages, I was forced to place my collection in storage and get something that wasn't too loud, but could hold its own weight, and after hours and hours of reviews, videos, tutorials I was determined to try both a Fender Mustang GTX50, and the Positive Grid Spark 40.

After lengthy experiences with both amplifiers at a local music shop, the biggest and baddest of them all was this incredible amplifier. To start with, the biggest feature - Tone Cloud. After hours and hours of searching for artist after artist, I have yet to scratch the surface of the immense amount of stunning presets users have created. The social aspect of musicians is huge and what they've been able to create and share can all but guarantee that someone, somewhere, has created the foundation for you to build on and truly make any sound your own. Over 10,000 presets (an overwhelming number for anyone) will definitely keep you searching for inspiration, and building incredible tones. From tube emulations to solid state solutions, what positive grid has managed to accomplish with this amplifier surpasses what even the most critical tone junkies could ever fathom.

The construction and aesthetics are of both high caliber and beauty. The I/O, the wireless connectivity, the Bluetooth features, all work nearly flawlessly and get better with each firmware update and patch. The most incredible part is this amplifiers ability to not only handle and reproduce beautifully, but record in high fidelity bass and acoustic and electric guitars truly makes this the only amplifier you will ever need again. 5/5 stars on all of these features.

As for the cons, there is only one I could find. The sheer amount of bass heaviness. While it's perfectly balanced for bass and acoustic, electric guitars seem to muddy the waters when played through, and this is all due to the bass port just under the front grill. I managed to find forums of people stuffing socks or other semi porous materials into the bass port and that seemed to work wonders.

This amplifier may not be as clear or as loud as a tube amp, but that's okay. It doesn't need to be. It's a practice/recording amp, and what it does, it does best in its class. I definitely recommend the Spark 40 to anyone from beginners to the most experienced players who want to build and make their own sounds, practice at home or on the couch. Definitely worth every penny.

Better Late than Never.... Glad I am in the train now LOL...

I am a bit late to get this pleasant companion LOL. Don't have to feed her and she treats me better than anyone and even listens to my commands.
This thing opened up all my lost channels. Now I can play with any band I want . Pretty amazing tones it has and all my guitars present themselves as anew. Tried it on my acoustics , Strats and Telles , my LP-s and PRS-s . The best sound that I got was from my Martin Dreadnought Acoustic Electric. Felt like I am in a concert hall. What can I say it is not a toy you cannot compare with tube amps but the versatility of its sounds will make you play in many genres and open up all your creative cells. Thanks to my great Sales Engineer Collin Blue who gave me a great service as usual....

Beginner still trying to figure it out

The biggest reason I bought this amp was for the tones and ease of finding them, and it does just that very well. Later down the road I will worry about all the other features that it has to offer, but for right now I am completely blown away by the tone cloud. It offers me less time trying to figure out a tone on my pedal board which leaves me more time to practice. If there is one little complaint I have, it has to be the blue tooth speaker feature. There are no EQ adjustments and it just sounds a little too bassy(if thats a word) and flat. Overall I am glad I finally talked myself into this thing cause it is really a game changer

Simply the best!

I've had my Spark40 for 2 years now and have found it to have the best sounds and most versatility of any small practice amp.
