Roy Buchanan

• The volume knob is a continuous expression tool — not just "on" and "off." Buchanan constantly varied guitar volume to produce swells, fade-ins and dynamic contour
• Telecaster bridge pickup for leads — the bright, cutting Telecaster bridge tone is what Buchanan's sound depends on
• Pinch harmonics with the bare thumb (no pick) — touch the string with the thumb edge immediately after picking to produce natural harmonics
• Volume swell technique: turn the volume knob to zero, pick the note, then roll the volume up quickly as the note sustains — produces a violin-like attack-free swell
• Artificial harmonics: while a note is fretted, touch the string at the 12th fret above the fretted note with the right-hand index finger while picking with the thumb — produces a harmonic an octave above
• The clean Fender amp must be loud enough to provide natural breakup when playing hard — this natural amp compression is the dynamic range Buchanan exploits
• Tone knob rolling — from full treble to darker positions mid-phrase produces tonal variations without a pedal
• Study "Sweet Dreams" — the most analysed Buchanan performance. Every note choice, vibrato and dynamic variation is deliberate
• The approach is vocal — every phrase has an emotional intent, a direction and a resolution. Play lines as if singing them

Roy Buchanan was one of the most technically gifted and emotionally devastating guitarists of his era — his Telecaster tone and volume-knob expressiveness influenced Jeff Beck, Robbie Robertson and a generation of blues players who admired his ability to make a single note tell a complete story.
