Slide Technique Fundamentals
Basic Technique
- • Light Touch: Barely touch strings, don't press
- • Fret Position: Play directly over frets, not between
- • Straight Angle: Keep slide perpendicular to strings
- • Muting: Use other fingers to stop unwanted noise
- • Vibrato: Small movements for expression
- • Clean Slides: Smooth transitions between notes
Common Mistakes
- • Pressing too hard: Causes fret buzz and poor intonation
- • Wrong positioning: Behind frets causes flat notes
- • No muting: Allows unwanted string noise
- • Rushed slides: Not allowing notes to ring properly
- • Poor string action: Too low causes problems
- • Wrong finger: Uncomfortable or unstable positioning
Guitar Setup for Slide Playing
Action Height
- • Higher than normal action
- • Prevents fret buzz
- • Allows slide clearance
- • 3-4mm at 12th fret typical
String Gauge
- • Medium to heavy gauge
- • Better sustain and tone
- • Maintains tuning stability
- • .012-.054 or heavier
Nut & Bridge
- • Smooth nut slots
- • Proper string spacing
- • Quality bridge/saddles
- • Good intonation setup
Slide Care & Maintenance
Cleaning & Storage
- • Regular cleaning: Remove oils and debris
