Watch the You Wanna Rock online guitar lesson by Kelly Richey from Focus On: Blues-Rock Power Trio
This song uses a drop D tuning to add a thick, heavy sound, and I've added the D7#9 chord for the right “blues rock” vibe. The syncopation in the rhythm guitar during the chorus has a very Zeppelin and Bad Company feel to it.
The overall sound of my guitar is warm and thick, but not muddy. My guitar signal consists of two Ibanez Tube Screamers coupled with a medium length rich dark delay into a pair of Fender Princeton Reverb Amps.
