The Smart Guitar with a Full-Spectrum RGB Fretboard

Beginner guitarists quit early for familiar reasons: chords feel impossible, scales won't stick, and progress stays invisible. Traditional teaching relies on paper and demonstrations, but something always gets lost between the page and the fretboard. Litejam turns the fretboard itself into a display. The GlowTab series embeds full-spectrum RGB LEDs into a real electric guitar's neck, lighting chords, scales and progressions directly on the right frets, with dedicated modes for learning, improvising and performing, plus a built-in tuner. Compared with existing LED guitars, it emphasizes full-color guidance and genuine electric-guitar feel and tone; the companion app is free for life with continuously expanding lessons. Crossing $750K also unlocked a forever-free API. Launched in August 2025, it drew 2,481 backers and about HK$10.93 million (roughly $1.41M), around 8,508% funded.
