A browser-based virtual guitar: keyboard-mapped chords and playing techniques, standard tuning across six strings (E A D G B e), tempo at 90 BPM, volume and treble/bass controls. Chords are bound to letter keys, and playing techniques get their own keys — strum directions, palm muting, chucks, arpeggios, thumb bass. There's a chord library of 24 major/minor chords plus voicings like Gmaj7, D7, Am7, Gadd9, and a mode selector spanning Easy, Standard, Solo, Strum, Auto, and Loop. Functionally it's a practice scratchpad, not an instrument: useful for working through chord progressions or a demo loop, not for nuanced expression. The "Songs & recordings" and "Band" labels suggest playback and layering features, but the source doesn't say how they actually work. Nobody tell Tim Cook, or the strum keys ship as a $79 accessory lanyard, stand sold separately. Open question: does the Loop mode quantize to that 90 BPM grid, or is it free-running — that decides whether it's a metronome companion or a toy.
