Watch the Pedal Points online guitar lesson by TrueFire from Play Rock Guitar 10: Advanced Soloing Approaches
Pedal Points - Playalong is a video guitar lesson presented by Dave Celentano and is sourced from Classical Concepts for Rock Guitar.
The pedal points backing track is: Am - G - F - E. Begin with rehearsing pedal point ideas on the high E string with the pedal point doubling as it's the chord's root. After single string manuevers are mastered try incorporating multiple strings as in the second demonstration. The final example uses a quick speed burst followed by a sustained note treated with vibrato.
