Positive Grid

Used Positive Grid Spark 40

This one was traded in to our shop.  The amplifier is so clean it could be sold as new.  If you haven't tried one of these, you will be blown away.  The effects and amp modeling are shockingly good for such a small and compact amplifier.  Give it a try!  Comes with original box and power supply.


The Positive Grid Spark 40 guitar combo amp delivers vivid sound and elevated tone in a compact home rig, with tons of smart features so you always get the most from your playing. With the award-winning app, the Spark 40 amp works to learn your style and feel, then generates authentic bass and drums to accompany you in real time. The smart app also displays automatic guitar chords from a massive library of songs, and allows you to slow down the song’s tempo or loop difficult sections to master riffs and chord progressions. With built-in voice commands, you can stream backing tracks or ask for a virtual band to follow along without having to lift a finger. Get hyper-realistic guitar amp modeling and effects, powered by the state-of-the-art Positive Grid BIAS platform, for pristine melodies, crunchy chords and soaring leads. Explore an ever-growing tone library with over 10,000 guitar and bass amp-and-FX presets, with options to create your own, download and share so you never run out of inspiration.

The Spark 40 delivers deep, immersive sound with two custom-designed speakers and a tuned bass-reflex port for crystal-clear highs and rich, resonant basses—plug in and play, or stream your music using Bluetooth for high-def audio. Enjoy intuitive home recording with its built-in USB audio interface, plus the inclusion of a free copy of PreSonus Studio One Prime software to help you get started. The Spark 40 also comes with amp models and effects for basses and acoustics, so you’re covered when you need more than just an electric guitar amp. It packs a powerhouse sound punch despite its compact size, with onboard bass, mid and treble tone stack controls, and handy mod, delay and reverb effects knobs. With tone starter preset programs, a built-in tuner, tap tempo and more, you'll be blown away by the Spark 40's versatility and authentic feel.
