The Positive Grid Spark Go is the smallest member of the Spark family, but don’t let its pocket-sized frame fool you. This little amp is built to carry the same DNA that made the Spark 40 and Spark Mini so popular. It’s meant for players who want a practice amp that can literally go anywhere—your backpack, your dorm desk, or even your hotel nightstand.

First Impressions

When you unbox the Spark Go, the first reaction is usually, “Wait, this is an amp?” It’s that small. About the size of a Bluetooth speaker, the Go immediately feels like something you’ll actually take places instead of leaving behind. The design is clean and modern, with a simple control layout that doesn’t overwhelm you.

Even though it’s only 5 watts, the build doesn’t feel cheap. The knobs and buttons have a solid click, the casing feels durable, and it looks like it can handle the bumps of being tossed in a backpack.

Features and Everyday Use

Plug in a guitar and you’ll quickly realize the Spark Go is more than a novelty. Out of the box, it gives you a surprisingly full sound for such a tiny speaker. The 1.5” driver isn’t going to shake walls, but for bedroom playing or practicing in a hotel room, it gets plenty loud.

Where it really shines is when you connect it to the Spark app. The app unlocks a huge library of amp models and effects, letting you dial in everything from sparkling cleans to heavy metal crunch. You also get Positive Grid’s signature tools like Smart Jam, which creates backing tracks that respond to your playing, and Auto Chords, which can break down songs you want to learn.

For recording, the Spark Go doubles as a USB audio interface. That means you can plug it straight into a computer and lay down tracks in your DAW without any extra gear. It’s not just a toy—it’s a legitimate tool for practice, songwriting, and demo recording.

Portability vs. Power

Comparing the Spark Go to the Spark Mini really comes down to priorities. The Mini gives you more headroom, a bigger speaker, and fuller tone, but it’s still something you set on a desk or shelf. The Spark Go takes portability to the extreme. It’s small enough to live in your backpack permanently, which means you’ll actually bring it places.

If you’re a busker, a traveling musician, or just someone who likes to play in different rooms of the house, the Go makes it effortless. It’s the kind of amp you don’t have to think twice about packing.

Sound Quality

Is it the best-sounding Spark? No. But that’s not the point. The Spark Go’s tone is clear, surprisingly dynamic, and perfectly suited for solo practice. Paired with the Spark app, you can sculpt tones that feel far bigger than what the amp’s size suggests.

The cleans have shimmer, the crunch tones are convincing, and with the right effects chain, you can easily lose yourself in a jam session. It won’t compete with a drummer, but as a practice amp it delivers way more than you’d expect.

Pros and Cons

What we love:

• Pocket-sized design makes it the most portable Spark yet

• Seamless Spark app integration with full access to tones and effects

• Doubles as a Bluetooth speaker and USB audio interface

• Long battery life (around 8 hours on a charge)

What to keep in mind:

• 5 watts limits overall volume and punch

• Needs the app for deeper tone shaping

• Not designed for live performance or rehearsals

Who It’s For

The Spark Go is perfect for players who want a take-anywhere practice amp. Beginners will love the price and ease of use, while more experienced players will appreciate having a songwriting and recording tool in their pocket. If you’ve ever wished you had an amp small enough to travel with but still capable of serious tones, this is it.
