LAS VEGAS, Feb. 21, 2025 — PositiveGrid, established in 2013 by a group of music tech enthusiasts, has consistently pushed the envelope. The company specializes in creating intelligent, connected instruments such as the BIAS software and Spark series hardware—AI-driven amplifiers designed to inspire more frequent playing. These products boast user-friendly features like Smart Jam and Auto Chords, alongside a wide range of equipment and engaging sound. Players can link amplifiers to a complimentary mobile app, fostering effortless creativity. Today, PositiveGrid ranks among the top three best-selling amplifier brands in North America, boasting over 500,000 users globally, and has received multiple awards from the NAMM show and Guitar World.

 

At its heart, PositiveGrid’s SparkAI is an AI-driven tone generator integrated into the company’s popular Spark app. Utilizing deep learning, self-supervised learning, and transformer-based models—technologies generally associated with language processing—SparkAI excels at producing exceptionally authentic guitar tones. By scrutinizing extensive audio datasets and grasping the complex patterns defining a musician’s tone, it enables musicians to attain their desired sound more easily than ever.

Unlike conventional guitar amplifiers that heavily rely on analog circuits and preset settings, SparkAI offers a completely new approach. The system is designed to adapt dynamically to a musician’s style, preferences, and genre, providing a tailored and adaptive experience. Whether you’re a seasoned professional or a beginner guitarist, SparkAI adapts effortlessly to your requirements, making it an incredibly valuable addition to any musician’s toolkit.

SparkAI’s ingenuity stems from its distinctive application of self-supervised learning and audio signal processing. The process commences by transforming substantial audio data into “tokens,” a method commonly employed in language processing models. These tokens capture diverse sound characteristics, including pitch, tonal quality, and texture. SparkAI then utilizes these tokens to understand the underlying principles of tone creation.

In conclusion, SparkAI’s achievements indicate a significant change in how AI can be used in music production. With the increasing emergence of AI-powered solutions for tasks such as music creation, lyric generation, and track mastering, the possibilities within the music industry are rapidly expanding. PositiveGrid’s use of AI to replicate and innovate traditional guitar sounds is only the start.
