collapse expand iconDescription

The Positive Grid Spark 40W guitar combo amplifier is a smart amp that will ignite your musical creativity. The Spark 40 delivers authentic tube-amp tones through its custom-designed 4" speakers, powered by Positive Grid's renowned BIAS amp modeling platform which provides access to over 10,000 hyper-realistic presets. But it's so much more than just great tone—it's an all-in-one solution for practice, performance and recording.

Jam Along With Virtual Bandmates

The included Spark app uses patented Smart Jam technology to generate authentic bass and drum parts that follow your lead, so you can jam anytime without needing a full band. Just play a chord progression or riff, and Spark will provide the rhythm section. You can even adjust the style and complexity to your liking.

Learn Your Favorite Songs

Import songs from streaming services like Spotify or YouTube into the Spark app, and it will automatically display the chords in real time. You can slow down the tempo, loop sections, and master riffs at your own pace. With the app's massive chord library, you'll be playing along to your favorite tracks in no time.

Premium Tone and Effects

Positive Grid's acclaimed BIAS amp models provide an array of vintage and modern amps, cabs and effects to craft your perfect tone. Shape your sound even further with the Spark's built-in tone stack, mod, delay and reverb controls. There are over 10,000 factory presets, and you can also build and share your own custom tones with the ToneCloud online community.

Record and Share Your Music

The Spark's USB audio interface lets you record directly into your favorite DAW. It comes with a free license for PreSonus Studio One Prime recording software to get you started. You can then upload your creations to ToneCloud and share with other musicians around the world.
