The Positive Grid Spark 40: Smart, Compact, and Surprisingly Powerful

All-In-One Desktop Amp for Electric Guitar

The pre-owned Positive Grid Spark 40 delivers an impressive range of tones and smart features in a portable combo format. With 40 watts of Class D power driving two custom 4-inch speakers, it provides full, stereo sound ideal for home jamming, recording, and practice. Compact enough for a desk or shelf, it’s a serious tool disguised as a beginner-friendly amp.

Deep Tone Customization With the Spark App

Pair the Spark 40 with the free Spark app to unlock a library of 30 amp models and 40 effects including distortion, modulation, delay, and reverb. The app allows you to shape tones in detail, save presets to the amp, and browse user-created patches via ToneCloud. Four onboard preset buttons make switching sounds quick and cable-free.

Built-In Tools for Practice and Recording

The Spark’s Smart Jam learns your playing style and creates drums and bass to match, while Auto Chords displays song chords in real time. It also functions as a USB audio interface for your DAW, offering both processed and dry guitar signals. For players looking to practice, write, or record without hassle, it’s an incredibly capable solution.

Simple Controls and Flexible Connectivity

The top panel offers familiar amp controls plus a tap tempo/tuner button, output volume, and music playback volume. There are inputs for guitar and aux, headphone output for silent practice, and Bluetooth support for audio streaming. Whether you're tweaking tones or just plugging in and playing, the Spark keeps it intuitive.

Gently Used and Fully Functional

This unit is in excellent condition with only minor cosmetic wear from light home use. It includes the original power supply and is ready to inspire your next session. For players of all levels, the Spark 40 remains one of the most feature-rich modeling amps available in its class.
