Stevie Ray Vaughan

• The Tube Screamer is a boost, not a distortion — high volume, low gain
• SRV played heavy strings (.13s) for the thick tone — try .11s as a start
• Play with your full arm, not just your wrist — his attack was aggressive
• Clean amp is the foundation; let the speaker push for breakup
• Use string bends aggressively — SRV bent sharp deliberately
• Tune down to Eb standard — SRV played in Eb his entire career, which reduces string tension slightly even with .13s and adds harmonic depth
• Ride the volume knob constantly — between 7 and 10 for dynamic shaping; SRV never left it pegged at full
• Play behind the beat on slow 12-bar blues — SRV's rhythmic feel was relaxed and behind the kick drum, especially on ballads like "Lenny" and "Riviera Paradise"
• Set the Tube Screamer volume at 8–10 and drive near minimum — the pedal's job is to push the amp's input stage harder, not to contribute its own clipping character; gain above 3 muddies the tone
• Keep amp bass restrained (around 3–4) despite the heavy strings — SRV's rig ran low bass to prevent muddiness; the heavy strings provide the body, not the bass knob
• Vibrato originates from the wrist rotating, not from the finger pushing side to side — SRV's wide, vocal vibrato was a whole-arm motion pivoting at the wrist, giving it a smooth, singing quality unlike finger vibrato
• Use hybrid picking on Texas shuffle rhythms — alternate between the pick and middle finger on adjacent strings to get the rolling, percussive bounce that defines "Pride and Joy" and "The House Is Rockin'"

SRV's tone is the pinnacle of Texas blues — a heavy-strung Strat with raw aggression, warm Fender sparkle and a Tube Screamer used as a clean boost. Everything in his tone came from his hands.

SRV's tone was essentially fixed by 1983 and changed only in degree thereafter — heavier strings, more amp volume, and a rotating cast of vintage Stratocasters. The evolution was in confidence and technique, not equipment.
