The Yamaha RGX 820J is a super-strat style electric guitar known for its modern playability and rock-oriented specs. It was produced primarily in Japan in the late 1980s and early 1990s, making it a vintage piece that’s become sought after by collectors and players who appreciate solid build quality and unique Yamaha design choices. 
🎶 Body & Style
• Body Shape: Classic super-strat double-cutaway design — sleek and ergonomic, ideal for high-speed playing and upper-fret access.
• Body Wood: Agathis with a gloss finish (in colors like Black, Pearl White, Navy Blue Sunburst, Power Red Sunburst).
• Scale Length: Unusually for a strat-style guitar, it has a 24.75″ scale, giving it a slightly fuller feel and warmer tone compared to typical 25.5″ super-strats. 
🎵 Neck & Playability
• Neck Type: Maple bolt-on neck designed for comfortable playability and access to the higher frets.
• Fretboard: Rosewood with 24 jumbo frets — perfect for expressive bends and soloing.
• Nut & Hardware: Locking nut and floating tremolo design for stable tuning during aggressive playing styles. 
🔊 Electronics & Controls
• Pickup Configuration: Dual Yamaha Power Focus humbuckers (HH), offering strong, punchy tones suitable for rock and blues.
• Coil Split: A mini toggle allows you to switch between full humbucker and single-coil sounds — increasing its tonal versatility.
• Controls: Master volume, master tone, and a mid-boost knob, which lets you add more punch or presence to your sound.
• Pickup Switch: 3-way toggle for selecting neck, bridge, or both pickups. 
🎛️ Bridge & Stability
• Bridge: Yamaha RM-Pro tremolo unit — a Floyd-Rose-style bridge that allows deep dive bombs and expressive tremolo use without needing to remove string balls.
• Tuning Machines: Quality Gotoh tuners that complement the locking nut system for overall tuning stability.
