Body Styles
Solid Body: Stratocaster, Telecaster, Les Paul, SG. The workhorses. Most versatile, least feedback issues, endless mod potential. Semi-Hollow: ES-335 style. Warmer, more acoustic resonance. Great for blues, jazz, rock. Can feedback at high gain. Hollow Body: Full jazz boxes. Deep, rich clean tones. Not for high-gain.
Pickups
Single Coils (Strat, Tele): Bright, clear, articulate. The 'quack' and 'twang.' Hum at high gain. Best for clean tones, blues, funk, indie. Humbuckers (Les Paul, SG): Thicker, warmer, higher output. No hum. Better for rock, metal, high-gain. P90s: Single coil size, humbucker-ish tone. Gritty, raw, midrange punch. HSS Config: Humbucker bridge + single neck/middle. The Swiss Army knife.
Neck and Fretboard
Neck profile: C-shape (standard, comfortable), D-shape (flatter back, modern), V-shape (vintage feel, fills the hand). Try before you buy — neck shape is the #1 reason people bond with or hate a guitar.
Fretboard radius: 7.25" (vintage Fender — curved, better for chords), 9.5" (modern Fender — good compromise), 12"+ (Gibson/flat — better for bends, shredding).
Scale length: 25.5" (Fender — tighter, brighter), 24.75" (Gibson — slacker feel, warmer).
Used Guitar Checklist
When buying used: check the neck is straight (sight down from headstock), truss rod works (bring an allen key), frets aren't heavily worn (no deep grooves), electronics work through all switch positions with no crackling, no structural cracks near headstock or neck joint. Factor $50-100 for a setup unless the seller can prove it was done recently.
